実験手順

In a manner analogous to the procedure set forth in Scheme II, step A, hydrogenate ethyl 4-cyano-1-methyl-3-[4-(phenylmethoxy)phenyl]-5-(trifluoromethyl)pyrrole-2-carboxylate, (intermediate prepared in example A-237) using Pearlman's catalyst and 60 psi of hydrogen gas in 1:1 ethanol/THF for 11 hours. Filter the reaction through diatomaceous earth and concentrate in vacuo. Purify the residue via radial chromatography eluting with ethyl acetate and hexane to provide the title compound. MS (m/e): 337.0 (M−1) 1H NMR: 7.20 (d, 2H, J=8.3 Hz), 6.84 (d, 2H, J=8.8 Hz), 5.85 (s, 1H), 4.16 (q, 2H, J=7.0 Hz), 4.05 (s, 3H), 1.07 (t, 3H, J=7.0 Hz)
