実験手順

From pivalic acid (R)-6-[2-(ethoxycarbonylmethylamino)-4-methoxyphenyl]-5,6,7,8-tetrahydronaphthalen-2-yl ester (150 mg) and 4-benzyloxycarbonylmethylbenzoic acid (138 mg), according to an analogous synthetic method to Preparation Example 154, obtained was pivalic acid (R)-6-{2-[(4-benzyloxycarbonylmethylbenzoyl)ethoxycarbonylmethylamino]-4-methoxyphenyl}-5,6,7,8-tetrahydronaphthalen-2-yl ester (200 mg). A solution thereof in methanol (5 ml) was subjected to a catalytic reduction in the presence of 10% palladium-activated charcoal (40 mg) for 2 hours at room temperature under hydrogen atmosphere at ambient pressure. After filtration through celite pad, the solution was concentrated in vacuo to provide the title compound (170 mg).
