Participants

Reaction Steps

A mixture of 2.82 g (0.01 mole) of 2,4-diamino-5-(3'-hydroxy-4'-methoxybenzyl)pyrimidine hydrochloride, 3.36 g (0.01 mole) of N1 -(3-bromopropyl)-N4 -acetylsulfanilamide, 2.76 g of anhydrous K2CO3, and 20 ml of dimethylformamide is heated with stirring at 100° for 18 hr. The mixture is concentrated in vacuo to a dark oil, which is shaken with a mixture of water and chloroform. The oily material which remaines insoluble in the water and chloroform is chromatographed on silica gel. Elution with chloroform-methanol, (85:15) gives fractions containing 0.55 g (11%) of 2,4-diamino-5-{3'-[3"-(N4 -acetylsulfanilamido)propoxy-4'-methoxybenzyl}pyrimidine, m.p. 96°-98°. Spectral data are consistent with the proposed structure.
