Reaction Steps

To a round bottomed flask was added 6-(4-chlorophenyl)-1-methyl-4H-benzo[c]isoxazolo[4,5-e]azepin-4-amine (218 mg, 0.67 mmol). The flask was purged with nitrogen, MeCN was added (7 mL), and the solution was cooled to 0° C. Ethyl isocyanate (128 μL, 1.62 mmol) and triethylamine (244 μL, 1.75 mmol) were added and the reaction was allowed to warm to ambient temperature and stirred for 2 h. The reaction was quenched with a 1:1 mixture of sat. aq. NaHCO3:brine and extracted with EtOAc. The organic layer was dried over Na2SO4, filtered, concentrated and purified on a Biotage (isocratic elution 40% EtOAc: 60% Hexanes) to provide the title compound as white solid (220 mg). LC/MS m/z 395 [M+H]+.
