実験手順

To 4-ethylamino-2-methylthio-5-pyrimidinemethanol (6.44 g, 32.4 mmol) in 600 mL of chloroform was added manganese oxide (21.0 g, 241 mmol) over 3 minutes. The suspension was stirred at room temperature for 2 hours, and an additional 5.5 g of manganese oxide was added. Stirring was continued for 4.5 hours. The mixture was then filtered through celite washing with chloroform. The filtrate was concentrated in vacuo to give 6.25 g (97%) of 4-ethylamino-2-methylthio-5-formylpyrimidine; mp 58°-61° C.
