Abstract: | The reaction of 5-amino-4-chloro- and -4-methoxy-6~mercaptopyrimidines with 4-methoxy-, 4-amino-, and 2,4-diethoxyphenacyl chlorides has yielded 5-amino-4-chloro- and -4-methoxy-6-phenacylthiopyrimidines. The reaction of 2, 5-diamino-4-methyl-6-mercaptopyrimidine with 4-methoxyphenacyl chloride has yielded 2-amino-6-hydroxy-6-(4-methoxyphenyl)-4-methyl-5, 6-dihydropyrimido4, 5-b]-1,4-thiazine, and that with 4-aminophenacyl chloride has yielded the corresponding 7H-pyrimido4, 5-b]-1,4-thiazine.For part IV, see 1]. |
