Hydrochloric Acid → HCID 23152922, compound

Participants

Reaction Steps

To a solution of methyl 12-cyclohexyl-4-[2-oxo-2-(piperidin-1-yl)ethoxy]-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (254 mg, 0.49 mmol) in tetrahydrofuran (1 ml) was added a solution (1 ml) of 1M BH3 THF complex in tetrahydrofuran, and the mixture was stirred at room temperature for 3 hr. 2N Hydrochloric acid (2 ml) was added to the reaction mixture, and the mixture was stirred at 70° C. for 4 hr. The reaction mixture was allowed to cool to room temperature, and the reaction mixture was neutralized by adding 2N aqueous sodium hydroxide solution and saturated aqueous sodium hydrogen carbonate solution. Water was added, and the precipitated solid was collected by filtration and washed with water. The obtained solid was dried in vacuo to give methyl 12-cyclohexyl-4-[2-(piperidin-1-yl)ethoxy]-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (240 mg, yield 97%).
