実験手順
To a solution of 2,4-dichloro-5-methylpyrimidine (8.00 g, 49.1 mmol) and 3-amino-1-propanol (4.50 mL, 58.9 mmol) in ethanol (200 mL) was added sodium carbonate (26.0 g, 245 mmol). The solution was vigorously stirred at rt for 24 h. The mixture was filtered over Celite® and the filtrate concentrated under reduced pressure. The resulting solid was triturated with Et2O to give the product as a white solid (9.80 g, 99%). 1H NMR (400 MHz, CDCl3) δ 1.86 (qt, 2H), 2.00 (s, 3H), 3.55 (t, 2H), 3.64 (t, 2H), 4.92 (broad, 2H), 7.68 (s, 1H).
