Procedure

A solution of 6-cyclopentyl-5-methyl-nicotinic acid isopropyl ester (138 mmol, 558 μmol) in 25% aq. HCl (5 mL) is stirred at 65° C. for 24 h. The solvent is evaporated and the residue is dried under HV to give the title compound as a hydrochloride salt (163 mg) in form of a beige solid; LC-MS: tR=0.64 min; [M+1]+=206.50.
