On August 10, 2021, Moriyama, Akihiro; Kawabe, Yusuke; Otsuki, Shinobu; Takikawa, Yasushi published a patent.Computed Properties of 1198284-94-4 The title of the patent was Preparation of (hetero)arylimidazolone compounds as inhibitors of prolyl hydroxylases (PHDs). And the patent contained the following:
The (hetero)arylimidazolone compounds represented by the following formula I [m, u = independently 0, 1, 2, or 3; p, q = independently 1 or 2; r = an integer from 0 to 6; R1 = halo, C1-6 alkyl, cyano, hydroxy, or carboxy (m = 2 or 3, two or more R1s may be different from each other); E, G, Q, T are groups selected from the group consisting of the following (1) to (7): (1) E = CR2e, Q = CR2q, T = CR2t, G = N; (2) E = CR2e, G = CR2g, T = CR2t, Q = N; (3) E = CR2e, G = CR2g, Q = CR2q, T = N; (4) E = CR2e, Q = CR2q, G = T = N, (5) G = CR2g, T = CR2t, E = Q = N; (6) G = CR2g, Q = CR2q, E = T = N; and (7) E = CR2e, G = CR2g, Q = CR2q, T = CR2t; R2e, R2g, R2q, R2t = independently H, halogen, C1-6 alkyl, Halo-C1-6 alkyl, C1-6 alkoxy, halo-C1-6 alkoxy, hydroxy, CO2H, C1-6 alkoxycarbonyl, or (un)substituted NH2; ring W = C6-10 aryl, 5- or 6-membered ring heteroaryl, 9 or 10-membered ring heteroaryl, C3-8 cycloalkyl, or 3- to 8-membered heterocycloalkyl; ring Z = Q1, Q2, or Q3; Ra, Rb, Rc = independently H, halogen, C1-6 alkyl, cyano, Hydroxy, or carboxy; Rd = H or C1-6 alkyl; R3 = halogen, C1-6 alkyl, halo-C1-6 alkyl, C1-6 alkoxy, halo-C1-6 alkoxy, C2-6 alkoxy, C2-6 alkynyl, C1-6 alkylsulfanyl, C1-6 alkylsulfinyl, C1-6 alkoxysulfonyl, hydroxy, cyano, nitro, CO2H, C1-6 alkoxycarbonyl, or each (un)substituted or CONH2, etc.] or pharmacol. acceptable salts thereof. The compounds I or pharmacol. acceptable salts thereof have an inhibitory action on prolyl hydroxylases (PHDs) and are useful as therapeutic agents for inflammatory bowel disease such as ulcerative colitis and Crohn’s disease. Thus, (S)-3-[3-[6-[4-(methoxycarbonyl)phenyl]pyridin-3-yl]-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl]pyrrolidine-1-carboxylic acid tert-Bu ester was treated with 4 M HCl/1,4-dioxane solution at room temperature for 8 h to give (S)-3-[3-[6-[4-(methoxycarbonyl)phenyl]pyridin-3-yl]-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-1-yl]pyrrolidine which underwent reductive alkylation with 2-formylisonicotinic acid Me ester using NaBH(OAc)2 in the presence of Et3N in THF at room temperature for 2 h to give (S)-2-[[3-[3-[6-[4-(methoxycarbonyl)phenyl]pyridin-3-yl]-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-1-yl]pyrrolidin-1-yl]methyl]isonicotinic acid Me ester (II; R = Me). II (R = Me) was stirred with LiOH in aqueous methanol at 65° for 1 h, cooled to room temperature, treated with concentrated HCl, and stirred at 50° for 30 min to give (S)-2-[[3-[3-[6-(4-Carboxyphenyl)pyridin-3-yl]-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-1-yl]pyrrolidin-1-yl]methyl]isonicotinic acid II (R = H). II (R = H) showed IC50 of 0.12μM against human PHD2184-418. The experimental process involved the reaction of tert-Butyl 1-oxo-2,9-diazaspiro[5.5]undecane-9-carboxylate(cas: 1198284-94-4).Computed Properties of 1198284-94-4
