Reaction Steps

The titled compound was prepared employing the procedures described for the construction of 1-({2-[(1S,2S)-2-hydroxycyclohexyl]-3-oxo-2,3-dihydro-1H-benzo[d]isoindol-5-yl}methyl)-4-(pyridine-2-yl)piperidine-4-carbonitrile in Example 1, substituting tert-butyl 4-cyano-4-methoxypyridin-2-yl)piperidine-1-carboxylate for tert-butyl 4-cyano-4-pyridin-2-ylpiperidine-1-carboxylate. The resultant white solid gave proton NMR spectra consistent with theory and a mass ion (ES+) of 511.2715 for [M+H]+[calc'd for C31H35N4O3, [M+H]+=511.2704]: 1H NMR (400 MHz, CDCl3) δ 8.19-8.11 (m, 2H), 7.90-7.83 (m, 2H), 7.68 (s, 1H), 7.67-7.52 (m, 3H), 5.04-4.92 (m, 2H), 4.59-4.54 (m, 2H), 4.17-4.11 (m, 2H), 3.78-3.71 (m, 2H), 2.23-2.19 (m, 2H), 1.96-1.81 (m, 4H), 1.64-1.20 (m, 1H) ppm.
