실험 절차

100 μL of saturated aq. sodium bicarbonate was added to trans-7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepine-1-amine (9.5 mg, 0.03 mmol) and chloromethyl chloroformate (64.2 μL, 0.42 mmol) in 250 μL of CH2Cl2. The resulting mixture was stirred at room temperature for 18 h. Subsequently, ethyl acetate was added and the organic layer was washed with water, dried (Na2SO4) and evaporated to give trans-(7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)carbamic acid chloromethyl ester (9.9 mg, 88%). Data: (m/z)=393 (M+H)+.
