Reaction Steps

2,6-Diisopropyl-3-hydroxymethyl-4-(2-benzyloxyphenyl)-5-(pent-1-enyl)-pyridine (Example 162) (680 mg, 1.53 mmol) was dissolved in 15 mL of methylene 25 chloride under an argon atmosphere and treated with a mixture of Celite (661 mg) and pyridinium chlorochromate (“PCC”) (661 mg, 2 eq). The reaction was stirred at room temperature for 1.5 h. The suspension was filtered through a pad of silica and the pad was washed with 50 mL CH2Cl2 and the filtrate was combined and concentrated in vacuo to afford 572.4 mg of product (84%). 1H NMR (300 MHz, CDCl3): δ 0.70 (t, J=7.2 Hz, 3 H), 1.08-1.35 (m, 61 H), 4.9-1.93 (m, 1 H), 3.26-3.45 (m, 1 H), 3.87-3.97 (m, 1 H), 4.97-5.06 (m, 2 H), 5.27-5.50 (m, 1 H), 6.01-6.10 (m, 1 H), 6.94-7.34 (m, 9 H), 9.82 (d, J=3.6 Hz, 1 H).
