実験手順

To a stirred slurry of 0.2 g of a 60% dispersion of sodium hydride in mineral oil and 30 ml of N,N-dimethylformamide (DMF) cooled to 5° C. was added 1.95 g of N-(2-methoxyethyl)-2-chloro-5-(3,6-dihydro-3-methyl-4-trifluoromethyl-2,6-dioxo-1(2H)-pyrimidinyl)benzenesulfonamide (Compound #52) prepared according to the procedure set forth above Process B using 2-chloro-5-(3,6-dihydro-3-methyl-4-trifluoromethyl-2,6-dioxo-1(2H)pyrimidinyl)benzenesulfonyl chloride and 2-methoxyethylamine. After stirring for 1 hour at 5° C., 0.6 ml of iodomethane was added to the reaction mixture. After stirring at room temperature for 16 hours, the mixture was concentrated using a rotary evaporator. The resulting gummy residue was treated several times with water until a solid had formed. The solid was recrystallized from ethanol to give 1.3 g of the title compound as a whitecrystalline solid, m.p. 108°-110° C. Spectral data for this compound is found in Table I.
