Reaction Conditions:
with ammonium chloride in ethanol at 120; for 1 h;Microwave irradiation;
Steps:
ethyl 3-amino-3-iminopropionate hydrochloride (6*HCl)
A solution of ethyl 3-amino-3-ethoxypropenoate 10 (760 mg, 4.78 mmol) and NH4Cl (270 mg, 5.0 mmol) in EtOH (4.0 mL) was irradiated in a pressure-rated glass tube (10 mL) at 120 °C for 1 h (hold-time) using a CEM Discover microwave synthesizer by moderation of the initial magnetron power (200 W). After cooling in a flow of compressed air, the solution was filtered, evaporated in vacuo and triturated with diethylether to give the title compound1 (923 mg, 78%) as a colourless solid, which was used without further purification; νmax (neat) /cm-1 3300, 3095,1738, 1687; δH (500 MHz; d6-DMSO) /ppm 9.16 (2H, bs, NHH), 8088 (2H, bs, 2H, NHH), 4.15 (2H, q, J = 7.1 Hz, OCH2), 3.63 (2H, s, 2-H),1.22 (3H, t, J = 7.1 Hz, Me); δC (125 MHz, d6-DMSO) /ppm 166.7 (C), 163.6 (C), 61.9 (CH2), 38.2 (CH2), 14.4 (Me); m/z (EI) 130 (M•+).
