Participants

Reaction Steps

4.2 g (0.031 mole) of ethyl chloroformylformate were added dropwise at room temperature to a solution of 5.2 g (0.028 mole) of 2-amino indeno[1,2-d]thiazole in 250 ml of methylene chloride/2.5 ml of pyridine. The reaction mixture was stirred overnight, after which it was washed with water and dried over Na2SO4, the solvent was distilled off and the residue was recrystallized from acetone to give 5.0 g (62%) of a product of melting point 226°-228° C.
