Tert-butyl{3-[(2-methoxy-5-nitrophenyl)ethynyl]phenyl}carbamate → Tert-butyl{3-[2-(5-amino-2-methoxyphenyl)ethyl]phenyl}carbamate

Participants

Reaction Steps

tert-Butyl{3-[(2-methoxy-5-nitrophenyl)ethynyl]phenyl}carbamate (63 mg, 0.17 mmol) and 10% palladium on carbon (122 mg, 0.10 mmol) were stirred in N,N-dimethylformamide (3.0 mL) under an atmosphere of hydrogen for 16 hours. The mixture was diluted with ethyl acetate (9.0 mL) and filtered through celite. Evaporation of the filtrate gave the desired compound (55 mg, 94%). LCMS for C20H27N2O3 (M+H)+: m/z=343.2.
