실험 절차

A mixture of 5 g (0.04 mol) of 2-methyl-5-formylpyridine, 5.29 g (0.04 mol) of 2-thiouracil and 50 ml of concentrated hydrochloric acid was heated overnight. The solution was neutralized with sodium bicarbonate. The organic material in the resulting precipitate was taken up in methanol which was then evaporated to give 4.53 g (45%) of 4-hydroxy-2-mercapto-5-[(6-methyl-3-pyridinyl)hydroxymethyl]pyrimidine [MS(m/e)250]. This compound (2 g) is treated with zinc-acetic acid as in Example 9 to give the same end product.
