Participants

Reaction Steps

A mixture of ethyl 5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-1,2-benzisothiazole-3-acetate (0.600 g), 10% hydrochloric acid (20.0 mL), and 1,2-dichloroethane (2.00 mL) is boiled for 30 minutes while allowing the 1,2-dichloroethane to evaporate, cooled, and poured onto ice. The resultant aqueous mixture is filtered to obtain a solid. The solid is washed with water and air-dried to give the title product as a white solid (0.550 g, mp 240-242° C.).
