Reaction Steps

The title compound was prepared as described in General Method 1 using 5.0 mL of methyl acetoacetate, 2.0 g of NaH 60% dispersion in oil, 25 mL of 2.0M n-butyl lithium in hexane, 12.0 g of 4-benzyloxybenzaldehyde and 150 mL of tetrahydrofuran. After addition of the aldehyde, the reaction was stirred for 15 minutes at 0° C. then allowed to warm to room temperature overnight. The crude product was triturated from diethyl ether to afford a solid (m.p. 165°-166° C.). 'H NMR (CDCl3) δ2.91 (dd, 2H), 3.56 (dd, 2H), 5.09 (s, 2H), 5.65 (dd, 1H), 6.98-7.04 (m, 2H), 7.30-7.44 (m, 7H).
