Participants

Reaction Steps

To a solution of 12-cyclohexyl-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylic acid (500 mg, 1.38 mmol) in chloroform (10 ml) were added oxalyl chloride (0.15 ml, 1.66 mmol) and several drops of N,N-dimethylformamide. The mixture was stirred at room temperature for 2 hr and concentrated. Hexane was added to the obtained residue, and the precipitated solid was collected by filtration. The solid was washed with hexane to give 12-cyclohexyl-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carbonyl chloride (476 mg, yield 91%).
