Reference of 61367-07-5,Some common heterocyclic compound, 61367-07-5, name is Methyl trans-4-aminocyclohexanecarboxylate hydrochloride, molecular formula is C8H16ClNO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A stirred solution of 6-(5-cyano-1H-pyrazolo[3,4-b]pyridin-1-yl)-4-(cyclopropylamino)nicotinic acid (0.3 g, 0.94 mmol, Intermediate L), methyl (1R,4R)-4-aminocyclohexane-1-carboxylate hydrochloride (0.18 g, 0.94 mmol), HATU (0.54 g, 1.41 mmol) and DIPEA (0.54 mL, 1.41 mmol) in DMF (5 mL) was stirred at rt for 4 h. The reaction mixture was transferred then into ice water and the resulting precipitate was filtered off and dried under vacuum to give methyl (1R,4R)-4-(6-(5-cyano-1H-pyrazolo[3,4-b]pyridin-1-yl)-4-(cyclopropylamino)nicotinamido)cyclohexane-1-carboxylate as an off white solid (0.38 g, 88%). LC-MS (ESI+) m/z 460.2 (
The synthetic route of 61367-07-5 has been constantly updated, and we look forward to future research findings.
