HCID 670269742-(Isopropylamino)-6-methylisonicotinic acid hydrochloride

Procedure

A solution of 2-isopropylamino-6-methyl-isonicotinic acid ethyl ester (3.90 g, 17.5 mmol) in 32% aq. HCl (100 mL) is stirred at 70° C. for 5 h before it is cooled to rt and concentrated. The residue is dried under HV to give 2-isopropylamino-6-methyl-isonicotinic acid hydrochloride (4.20 g) as an orange resin; LC-MS: tR=0.52 min; [M+1]+=195.09.
