Hydrochloric Acid → Ethyl 2-methylpropanimidate--hydrogen chloride (1/1)

Participants

Reaction Steps

Isobutyronitrile (1 g, 14.5 mmol) was dissolved in anhydrous ethanol (30 mL) under an atmosphere of Ar. The solution was cooled to 0° C., saturated with HCl gas, stirred for 6 h, allowed to warm to RT, and stirred for 6 h. The solvent was removed in vacuo to afford ethyl isobutyrimidate hydrochloride (1.8 g, 82%) as a colorless solid. 1H NMR (400 MHz, DMSO-d6): δ 11.78 (br s, 1H), 11.05 (br s, 1H), 4.40 (q, J=7.0 Hz, 2H), 2.93-2.92 (m, 1H), 1.33 (t, J=7.0 Hz, 3H), 1.16 (d, J=6.9 Hz, 6H).
