Participants

Reaction Steps

A solution of 2-cyclopentyl-6-methoxy-isonicotinic acid methyl ester (3.19 g, 13.6 mmol) in 7 N NH3 in methanol (50 mL) is stirred at 60° C. for 18 h. The solvent is removed in vacuo and the residue is dried under HV to give crude 2-cyclopentyl-6-methoxy-isonicotinamide (3.35 g) as a pale yellow solid; LC-MS**: tR=0.57 min, [M+1]+=221.38.
