Reaction Steps

To a suspension of 4-hydroxymethyl-6-nitro-2H-1,4-benzoxazin-3(4H)-one (22.42 g) in chloroform (50 ml) is added a catalytic amount of triethylamine. The mixture is stirred at ambient temperature, treated dropwise with thionyl chloride, and stirred at 60° C. for 6 hours. The reaction mixture is made free form insoluble materials by filtration and the filtrate is poured into water. The separated chloroform layer is washed with water, saturated sodium bicarbonate solution and saturated sodium chloride solution successively, dried, and evaporated to obtain 4-chloromethyl-6-nitro-2H-1,4-benzoxazin-3(4H)-one (17.23 g).
