Participants

Reaction Steps

To a solution of methyl 2-[(12-cyclohexyl-3-methoxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carbonyl)amino]-2-methylpropionate (3.00 g, 6.11 mmol) in tetrahydrofuran (20.0 ml) and methanol (20.0 ml) was added 2N aqueous sodium hydroxide solution (10.00 ml, 20.00 mmol) at room temperature, and the mixture was stirred overnight. To the reaction mixture were successively added 2N hydrochloric acid (11.00 ml, 22.00 mmol), water and methanol, and the mixture was stirred at room temperature for 30 min. The precipitate was collected by filtration, washed with water, and dried in vacuo to give 2-[(12-cyclohexyl-3-methoxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carbonyl)amino]-2-methylpropionic acid (2.60 g, yield 89%).
