Procedure

A mixture of 1.6 g of N-methyl-N-(2-propenyl)-2-chloro-5-(3,6-dihydro-3-methyl-4-trifluoromethyl-2,6-dioxo-1(2H)-pyrimidinyl)benzenesulfonamide (Compound #29), prepared by process C from Compound #28 and iodomethane, 100 ml of ethyl acetate and 200 mg of 5% palladium/carbon catalyst was hydrogenated in a Paar® apparatus at 28 psi of hydrogen. After 30 minutes, the catalyst was filtered and solvent removed from the filtrate by rotary evaporation. The glassy residue was treated with ethanol to give 1.4 g of the title compound as a light gray powder, m.p. 143.5°-145° C.
