Reaction Steps
The title compound was prepared as described in General Method 1 using 13.67 g methyl acetoacetate, 8.5 g of NaH 60% dispersion in oil, 73.6 mL of 1.6M n-butyl lithium in hexane, 10 g of benzaldehyde, and 300 mL of tetrahydrofuran. After addition of the aldehyde, the reaction was stirred 15 minutes at -78° C. then allowed to warm to room temperature overnight. A solid was filtered off after concentration (m.p. 145°-146° C.). 1H NMR (CDCl3) δ 2.8-3.05 (m, 2 H), 3.5 (d, 1 H), 3.7 (d, 1 H), 5.7 (dd, 1 H), 7.3-7.5 (m, 5 H).
