Reaction Conditions

Reaction Steps

A mixture of 2-chlorobenzenethiol (8.0 g.), ethyl 2-(2-nitro-3-chlorophenyl)acetate (12.2 g.), anhydrous potassium carbonate (7.5 g.) and dry dimethylformamide (50 ml.) was stirred for an hour at 85° C. The reaction mixture was poured into water (300 ml.) and extracted with diethyl ether. The extract was washed with a saturated aqueous solution of sodium chloride, dried over magnesium sulfate and evaporated under reduced pressure. The oily residue was pulverized and recrystallized from methanol (20 ml.) to give the captioned compound (11.6 g.). mp 78° to 80° C.
