EXAMPLE 7 3,6-bis(n-hexylthio)-2-pyridinecarboxylic acid To 300 ml of DMSO was added 84.5 g of powdered NaOH with vigorous stirring followed by the addition of 150 g of n-hexyl mercaptan. The anion of the mercaptan was allowed to form and then 111 g of 3,6-dichloro-2-pyridinecarboxylic acid in 110 ml of DMSO was added through a dropping funnel. the temperature was increased during addition to 135 C. and maintained at that temperature for 21/2 hours. Upon cooling the brown solution was poured into three volumes of water. The resulting solution was acidified with HCl and extracted with 1,1,1-trichloroethane. The organic layer was dried over MgSO4 and the solvent removed on a rotary evaporator. The reaction yielded 155 g (68% yield) of 3,6-bis(n-hexylthio)-2-pyridinecarboxylic acid as a dark oil which solidified on standing; m.p. 40-42 C.
