4-Acetoxy-3-fluorobenzoic acid → Pivalic acid (R)-6-{2-[ethyl(3-fluoro-4-hydroxybenzoyl)amino]-4,5-dimethoxyphenyl}-5,6,7,8-tetrahydronaphthalen-2-yl ester

Participants

Reaction Steps

Synthesized from pivalic acid (R)-6-(2-ethylamino-4,5-dimethoxyphenyl)-5,6,7,8-tetrahydronaphthalen-2-yl ester and 4-acetoxy-3-fluorobenzoic acid according to an analogous synthetic method to Preparation Example 154, pivalic acid (R)-6-{2-[(4-acetoxy-3-fluorobenzoyl)ethylamino]-4,5-dimethoxyphenyl}-5,6,7,8-tetrahydronaphthalen-2-yl ester (537 mg) was used according to an analogous synthetic method to Preparation Example 155 to provide the title compound (298 mg).
