Reaction Steps
Following General Procedure D, Compound 75 (100 mg, 0.18 mmol) and tert-butyl 3-(aminomethyl)azetidine-1-carboxylate (62 mg, 0.31 mmol) were converted into the carbamate product. The crude carbamate product was treated with CF3CO2H and purified using neutral alumina prep TLC, eluting with 5% NH3-MeOH and 95% CH2Cl2 to isolate the title compound.
