Reaction Steps

10.0 g of 6-(chloromethyl)-2-triphenylmethyl-1,2-benzisoxazol-3(2H)-one, 35 mL of bromoethane and 2.42 g of sodium bromide were added to 80 mL of N-methyl-2-pyrrolidone, and this was stirred for 1.5 hours at 55-60° C. After cooling the reaction mixture, 20 mL of 2-propanol and 50 mL of water were added dropwise and solids were filtered to obtain a white solid. The obtained white solid, 35 mL of bromoethane and 2.42 g of sodium bromide were added to 80 mL of N-methyl-2-pyrrolidone, and this was stirred for 1 hour at 55-60° C. After cooling the reaction mixture, 20 mL of 2-propanol and 50 mL of water were added dropwise and solids were filtered to obtain 9.04 g of 6-(bromomethyl)-2-triphenylmethyl-1,2-benzisoxazol-3(2H)-one in the form of a white solid.
