Procedure
A suspension of 3.5 g. of 6-[4-[(2-dimethylaminoethyl)aminosulfonyl]phenyl]-1,2-dihydro-2-oxonicotinic acid in 175 ml. of thionyl chloride is stirred at room temperature for 16 hours. The mixture is diluted with 300 ml. of hexane and the precipitate of 6-[4-[(2-dimethylaminoethyl)aminosulfonyl]phenyl]-1,2-dihydro-2-oxonicotinyl chloride hydrochloride is collected by filtration, washed with hexane and dried. The acid chloride is used as such without further purification.
