실험 절차

A mixture of 2-Chloro-4,5-diamino-6-methylpyrimidine (0.80 g, 5.04 mmol), trimethylorthobutyrate (1.2 ml, 7.6 mmol) and p-TsOH (0.08 g) in 2-methoxyethanol (24 ml) was heated in an oil bath at 140° C. for 24 hours. The product was isolated as described in Step 2 of Example 12 and purified by flash chromatography using EtOAc-hexane (1:1) to give the crystalline titled compound (0.5 g, 47%).
