Procedure
The alkene intermediate from Example 29F (1.64 g, 7.35 mmol) was converted to the alcohol by the method of Example 26F, followed by chromatography (7:3 hexane/ethyl acetate) provided the title compound. 1H NMR (300 MHz, CDCl3): δ 0.96-0.79 (m, 2H), 1.00-1.14 (m, 1H), 1.54-1.76 (m, 3H), 4.91-4.97 (m, 1H), 3.76 (t, J=6 Hz, 2H), 6.92 (d, J=9 Hz, 2H), 7.35 (d, J=9 Hz, 2H). MS (DCl—NH3) m/z 258 (M+NH4)+.
