ConditionsYield
With palladium 10% on activated carbon; hydrogen In methanol at 30℃; under 2250.23 Torr; for 18h;

Experimental Procedure
A mixture of G’ (60.0 g), 10 percent Pd/C (6.0 g) and methanol (0.60 L) was stirred under hydrogen (3 bar) at 30 °C for 18 hours. The palladium on charcoal was removed by filtration ant the solvent was removed to give H (40 g, 100 percent). 1 H NMR (CDCI3): δ 1 .29 (s, 3H), 1 .40 (s, 3H), 1 .58 (m, 1 H), 1 .65 (m, 1 H), 2.09 (m, 1 H), 3.60 (m, 1 H), 4.09 (m, 1 H), 4.41 (m, 1 H), 4.69 (m, 1 H) ppm.

98%
With palladium 10% on activated carbon; hydrogen In methanol at 20℃; for 14h;

Experimental Procedure
A solution of 17 (100 mg, 0.38 mmol, 1 eq) in methanol (2 mL) was hydrogenated for 14 h at r.t. over 10percent palladium on carbon (15 mg). The reaction mixture was then filtered, and the collected solids were washed with methanol (1 mL). The combined filtrate was concentrated under reduced pressure to give the title product as a colorless oil, which could be recrystallized by PE to give a white solid (60 mg, 92.3percent yield). 1H NMR (500 MHz, CDCl3) δ 1.29 (3 H, s), 1.40 (3 H, s), 1.61~1.66 (1 H, d), 2.06~2.13 (1 H, m), 2.63 (2 H, s), 3.60~3.61 (1 H, d), 4.09~4.10 (1 H, d), 4.40~4.42 (1 H, d), 4.68~4.70 (1 H, d).
