Procedure

A solution of 2,6-dichloroisonicotinic acid ethyl ester (14.0 g, 63.6 mmol) in diethylamine (25 mL) is stirred at 100° C. for 7 h. The volatile compounds are evaporated and the residue is purified by CC on silica gel eluting with heptane:EA 9:1 to give 2-chloro-6-diethylamino-isonicotinic acid ethyl ester (10.1 g, contains 2-chloro-6-diethylamino-isonicotinic acid methyl ester which forms during the transfer of the reaction mixture into a round bottom flask using methanol); LC-MS: tR=1.09 min.
