YieldReaction ConditionsOperation in experiment
47% In tert-butyl alcohol; at 75℃; for 4h;Inert atmosphere; Ethyl 7-(hydroxymethyl)imidazo[1,2-a]pyridine-3-carboxylate (3) A mixture of (2-aminopyridin-4-yl)methanol (1, 149 mg, 1.20 mmol) and <strong>[33142-21-1]ethyl 2-chloro-3-oxopropanoate</strong> (2, 144 mg, 0.956 mmol), in t-butanol (3 ml), was stirred at 75 C. under N2 for 4 h. After cooling down to room temperature, solvent was evaporated, and the residue was further purified with flash silica gel column, with EA/Hex (gradient up to 99:1), to provide the product as white solid (98 mg, 47%). 1H NMR (500 MHz, Chloroform-d) delta 9.04 (dd, J=7.0, 0.9 Hz, 1H), 8.08 (s, 1H), 7.63 (t, J=1.4 Hz, 1H), 6.91 (dd, J=7.1, 1.7 Hz, 1H), 4.71 (d, J=1.3 Hz, 2H), 4.32 (q, J=7.1 Hz, 2H), 1.34 (t, J=7.2 Hz, 3H); 13C NMR (126 MHz, Chloroform-d) delta 160.43, 148.28, 143.42, 140.81, 127.06, 115.67, 113.44, 113.34, 62.91, 60.49, 14.40; ESIMS m/z 221.5 [MH]+.
