Reaction Steps

The product from Step 15.a. (compound xxiv, where R3, R5 and R6 are H, R5 is 2-methoxyphenyl, and R7 is n-butyl) (650 mg, 1.49 mmol) was dissolved in HOAc (25 ml) containing 10% Pd on carbon (65 mg) and the mixture was hydrogenated under 30 psi H2 for about 6 hours. The catalyst was removed by filtration through diatomaceous earth and the filtrate was concentrated under reduced pressure to yield a pale yellow oil which crystallizes on standing (430 mg, 101%).
