Reaction Steps

To a stirred solution containing 18 mg (0.04 mmol) of 3-(benzyloxy)-6-methoxy-2-(10-(methoxymethoxy)decyl)-4-methylpyridine in 3 mL of methanol were added two drops of concentrated HCl. The reaction mixture was stirred at reflux for 16 h. To the mixture were added 3 mg of 20% palladium hydroxide on carbon (Degussa type E101 NE/N). The reaction mixture was stirred at room temperature under hydrogen atmosphere for 15 min. The reaction mixture was filtered through celite and the filtrate was concentrated under diminished pressure. The residue was purified by chromatography on a silica gel column (5×1 cm). Elution with 3:1 hexanes-ethyl acetate afforded the expected product as white solid: yield 8 mg (67%); mp: 80-81° C.; silica gel TLC Rf 0.50 (3:1 hexanes-ethyl acetate); 1H NMR (methanol-d4) δ 1.27 (br s, 12H), 1.49 (br s, 2H), 1.64 (br s, 2H), 2.41 (br s, 3H), 2.81 (br s, 2H), 3.51 (br s, 3H), 4.02 (br s, 1H) and 7.05 (br s, 1H); 13C NMR (methanol-d4) δ 16.59, 25.51, 28.13, 28.57, 28.92, 28.97, 29.09, 29.14, 29.24, 32.22, 56.39, 61.56, 107.60, 142.26, 145.27, 148.68 and 155.10; mass spectrum (APCI+), m/z 296.2220 (M+H) (C17H30NO3 requires 296.2226).
