Reaction Steps

A stirred solution of ethyl cyanoacetate (30 mL, 281 mmol) and EtOH (18.1 mL, 278 mmol) in anhydrous Et2O (28.1 mL), at 0° C., was bubbled with HCl gas until saturated. The reaction was stirred at 22° C. for 20 hours and then concentrated to give the title product. 1H NMR (400 MHz, CDCl3) δ 4.73 (q, J=7.1 Hz, 2H); 4.24 (q, J=7.2 Hz, 2H); 3.89 (s, 2H); 1.51 (t, J=7.0 Hz, 3H); 1.30 (t, J=7.2 Hz, 3H) ppm.
