Participants

Reaction Steps

To a stirred solution of 6.1 g (0.0232 mol) 3-(2,6-dimethylphenylamino)-4-methyl-5-methylthio-1,2,4-triazole in 150 ml toluene was added quickly 2.7 g (0.024 mol) chloroacetyl chloride. An exotherm ensued and the temperature rose to 100° C., followed by separation of an oil which solidified. The reaction mixture was stirred at 100°-105° C. for 1 hour, cooled and diluted with 50 ml saturated sodium bicarbonate and 20 ml dichloromethane. The clear organic layer was separated, dried over magnesium sulfate and evaporated under reduced pressure to give a clear oil. The oil was crystallized from ethyl ether to give 7.4 g of product, as a pale yellow solid, m.p. 145°-147° C. The product is tabulated in Table I as Compound No. 14-B.
