Reaction Steps

A solution of heptan-2-one (51 mg, 0.45 mmol), 1-p-tolylethanone (60 mg, 0.45 mmol), ethyl-2-cyanoacetate (51 mg, 0.45 mmol) and ammonium acetate (42 mg, 0.55 mmol) in anhydrous DMF (0.6 mL) was heated with stirring at 100° C. for 16 h. The reaction was diluted with EtOAc and washed with water. The solvent was removed in vacuo and the product was purified by preparative HPLC (MeOH/H2O/TFA) to provide the desired product (8 mg, 6%) as a white solid. LCMS Anal. Calc'd for C19H24N2O 297.41. found [M+H] 297.2. 1H NMR (500 MHz, CDCl3) δ 0.89 (t, J=6.87 Hz, 3H), 1.24-1.40 (m, 9H), 1.51-1.71 (m, 2H) 2.42 (s, 3H), 2.73-2.97 (m, 2H), 6.09 (s, 1H), 7.30 (d, J=7.70 Hz, 2H), 7.52 (d, J=7.70 Hz, 2H).
