Reaction Steps

A 50 mL flask was charged with a mixture of 3 (2.7 g, 15 mmol), 4-bromo butyric acid methyl ester (9.9 g, 55 mmol) and potassium carbonate (8.6 g, 62 mmol) in acetonitrile (25 mL). The mixture was stirred at room temperature for 72 hours followed by evaporation to dryness. The crude product was subjected to column chromatography (eluent: CH2Cl2:CH3OH (96:4)) to produce pure 4 (3.4 g, 94%). 1H NMR (CDCl3) δ0.89 (t, 3H), 1.20-1.39 (m, 9H), 1.69 (d, 2H), 1.89 (qv, 2H), 1.98 (t, 2H), 2.36 (t, 2H), 2.43 (t, 2H), 3.99 (d, 2H), 3.67 (s, 3H).
