実験手順
2-Dimethylamino-4-(2-aminoethyl)thiazole (1.7 g, see preceding preparation), formaldehyde (0.78 ml of a 37% solution in water, 9.6 mmol) and acetic acid (0.15 ml, 2.6 mmol) were combined in methanol (100 ml). After 2.5 hours at room temperature, the reaction mixture was treated with additional formaldehyde (0.15 ml, 1.8 mmol) and allowed to stir for an additional 16 hours. The reaction was then filtered, and the filtrate was concentrated in vacuo and purified by column chromatography (eluant: 89:10:1 of chloroform:methanol:concentrated ammonium hydroxide), providing the title product as a white solid (1.04 g, 5.7 mmol).
