1,1-dimethylethyl [2-({[5-(1-methyl-1H-pyrazol-5-yl)-3-thienyl]carbonyl}amino)-2-(1-naphthalenyl)ethyl]carbamate → N-[2-amino-1-(1-naphthalenyl)ethyl]-5-(1-methyl-1H-pyrazol-5-yl)-3-thiophenecarboxamide

Participants

Reaction Steps

A solution of 1,1-dimethylethyl [2-({[5-(1-methyl-1H-pyrazol-5-yl)-3-thienyl]carbonyl}amino)-2-(1-naphthalenyl)ethyl]carbamate (76 mg, 0.16 mmol) in TFA-DCM (3 mL, 1:2) was stirred at 25° C. After 30 min, the solution was concentrated with a toluene azeotrope and the residue neutralized through a silica plug (3% MeOH in DCM (1% NH4OH)) affording the free base of the title compound (14 mg, 23%) as a white solid.
