5-Methyl-1,3-cyclohexanedione (40 g, 0.32 mol) was dissolved in 500 ml of benzene at 70° C. The solution was heated at reflux for 2 hours, during which NH3 was bubbled through the reaction mixture and formed H2O was collected in a Dean-Stark trap. The mixture was then cooled to 0° C. and title product recovered by filtration, 39.8 g, m.p. 165°-169° C. 1H-NMR(DMSO-d6)delta(ppm): 0.98 (s, 3H), 1.6-1.88 (2H), 2.14-2.38 (2H), 3.14-3.6 (1H), 4.93 (s, 1H), 6.2-7.2 (m, 2H).
