Reaction Steps

The title compound was prepared as described in General Method 1 using 0.85 mL of methyl acetoacetate, 350 mg of NaH 60% dispersion in oil, 5 mL of 1.6M n-butyl lithium in hexane, 2.0 g of 2-phenoxy-1-phenyl ethanone and 60 mL of tetrahydrofuran. After addition of the ketone, the reaction was stirred for 15 minutes at 0° C. then allowed to warm to room temperature and stirred for 1 hour. The crude product was triturated from diethyl ether to afford a solid (m.p. 133°-135° C.). 1 H NMR (DMSO-d6) δ3.03 (d, 1H), 3.35 (d, 1H), 4.18 (dd, 2H), 4.90 (s, 1H), 6.92-6.95 (m, 3H), 7.24-7.49 (m, 7H), 11.56 (s, 1H).
