Reaction Steps

NaH (60%, 0.12 g, 2.90 mmol), 71 (1.24 g, 2.42 mmol) in DMF (30 mL), and 67 (0.91 g, 2.42 mmol) in DMF (10 mL) were reacted and worked up following the method of 72. Column chromatography (25:1 toluene/EtOAc) gave 1.67 g (85%) of 74 as an oil: NMR δ 0.74 (t, 3 H, J=7), 1.35-1.45 (m, 11 H), 2.00 (t, 2 H, J=7), 2.25 (s, 3 H), 2.28 (s, 3 H), 2.55 (s, 6 H), 2.56 (s, 6 H), 2.98-3.08 (m, 8 H), 6.90 (s, 2 H), 6.91 (s, 2 H), 7.15-7.44 (m, 15 H).
