Reaction Conditions

Reaction Steps

The title compound was prepared as described in General Method 1 using 3.1 mL of methyl acetoacetate, 1.2 g of NaH 60% dispersion in oil, 18 mL of 1.6M n-butyl lithium in hexane, 6.0 g of 3-(4-fluorophenyl)propiophenone and 200 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 4 hours. The crude product was triturated from diethyl ether to afford a solid (m.p. 155°-157° C.). 1 H NMR (CDCl3) δ2.23-2.29 (m, 2H), 2.42-2.52 (m, 1H), 2.67-2.78 (m, 1H), 2.97 (dd, 2H), 3.35 (dd, 2H), 7.34-7.47 (m, 5H), 6.91-7.07 (m, 4H).
