Reaction Steps

The title compound was prepared analogously to example A(1): where 2-{2-chloro-4-[2-(2-cyclopentyl-4,6-dioxo-tetrahydro-pyran-2-yl)-ethyl]-phenyl}-2-methyl-propionitrile from step 5 below, was substituted in place of 6-[2-(3-chloro-5-ethyl-4-methoxy-phenyl)-ethyl]-6-cyclopentyl-dihydro-pyran-2,4-dione and 2,5-dimethyl-2H-[1,2,4]triazole-3-carbaldehyde was substituted instead of 5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde in that example. 1H NMR (300 MHz, DMSO-d6): δ 1.47-1.74 (m, 8 H), 1.79 (s, 6 H), 2.01-2.11 (m, 8 H), 2.36-2.42 (m, 1 H), 2.56 (d, J=16 Hz, 1H), 2.60-2.66 (m, 2 H), 2.77 (d, J=16 Hz, 1 H), 3.53 (d, J=16 Hz, 1 H), 3.62 (d, J=16 Hz, 1 H), 7.25 (dd, J=8.2, 1.8 Hz, 1 H), 7.4 (d, J=1.8 Hz, 1 H), 7.45 (d, J=8.2 Hz, 1 H). Anal. Calcd. For C27H33ClN4O3.0.25H2O: C, 64.66; H, 6.73; N, 11.17. Found: C, 64.88; H, 6.74; N, 10.86. ESIMS (MH+): 498.
