Participants

Reaction Steps

2-[Methyl(2-thienylmethyl)amino]ethanol (0.017 mol, 3 g) and cyanoacetic acid (0.017 mol, 1.5 g) were dissolved in 200 mL of THF and DCC (0.019 mol, 3.8 g) was added. After 3 h, the resulting solid was removed and the filtrate was concentrated. The residue was passed through a six-inch silica plug using ether as solvent to give 4.0 g of product. 1H NMR (300 MHz) CDCl3: 7.25 (d, 1H), 7.0-6.8 (m, 2H), 4.33 (t, 2H) 3.76 (s, 2H), 3.47 (s, 2H), 2.70 (t, 2H), 2.35 (s, 3H).
