Reaction Steps
A solution of 1-benzyloxycarbonylmethyl-3,5-dichloro-6-methylpyrazinone (656 mg, 2.00 mmol), as prepared in the preceding step, 4-methylphenethylamine (380 mg, 2.81 mmol), triethylamine (405 mg, 4.01 mmol), and ethyl acetate (20 mL) was refluxed overnight. After cooling to room temperature, the solution was washed with 10% citric acid (×2). The aqueous solutions were back extracted with dichloromethane. The combined organic layers were dried (Na2SO4) and contracted to give the title compound as a yellow solid (854 mg, 100%). 1H NMR (CDCl3) δ 7.38-7.32 (m, 5H), 7.12 (s, 4H), 6.09 (s, 1H), 5.21 (s, 2H), 4.79 (s, 2H), 3.65 (dd, 2H, J=7.0, 13.0 Hz), 2.88 (t, 2H, J=7.1 Hz), 2.32 (s, 3H), 2.21 (s, 3H).
