実験手順

A mixture of 6-bromo-9H-purin-2-ylamine (2.4 g, 11 mmol), 4-bromo-2-chloromethyl-3,5-dimethyl pyridine (3.5 g, 15 mmol), K2CO3 (2.07 g, 15 mmol) and DMF (50 mL) was stirred at 50° C. for 2 h. Work-up and flash chromatography gave the title compound as a white solid (2.6 g, 56%). HPLC Rt: 5.415 min. 1H-NMR (CDCl3): δ 8.17 (s, 1H), 7.88 (s, 1H), 5.38 (s, 2H), 5.05 (s, 2H), 2.51 (s, 3H), 2.37 (s, 3H).
