Reaction Steps

The title compound was prepared as described in General Method 1 using 10 mmol of methyl acetoacetate, 11 mmol of NaH 60% dispersion in oil, 10.5 mmol of 1.6M n-butyl lithium in hexane, 10 mmol of hexanophenone and 28 mL of tetrahydrofuran. Upon concentrating the reaction a solid precipitated out which was triturated with ether and filtered (m.p. 123°-124° C.). 1H NMR (CDCl3) δ 0.83 (t, 3 H), 1.1-1.4 (m, 6 H), 1.9-2.0 (m, 2 H), 2.90 (d, 1 H), 2.92 (d, 1 H), 3.25 (d, 1 H), 3.35 (d, 1 H), 7.2-7.5 (m, 5 H).
