In benzene; | Example 1 8-(2,4-Dimethoxy-phenyl)-purine A mixture of 2 g of <strong>[13754-19-3]4,5-diamino-pyrimidine</strong>, 4 g of 2,4-dimethoxy-benzonitrile, 6 g of p-toluene sulfonic acid hydrate, and 40 ml of benzene was heated, whereby the benzene was distilled off. The residue was heated for 30 minutes at 120 C. After cooling the residue was triturated with 2 N ammonia and extracted with ethyl acetate. The ethyl acetate phase was extracted with 2 N hydrochloric acid, the aqueous phase was neutralized and again extracted with ethyl acetate, and subsequently the organic phase was extracted with 2 N sodium hydroxide solution. When the aqueous phase was neutralized, the product was precipitated and recrystallized from water. Yield: 0.15 g (3% of theory), M.P.: 221 C. (decomp). |
