Reaction Steps

The title compound was prepared analogously to Example B(97), 1-(2-Chloro-4-{2-[2-cyclopentyl-5-(5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-ylmethyl)-4-hydroxy-6-oxo-3,6-dihydro-2H-pyran-2-yl]-ethyl}-phenyl)-cyclopropanecarbonitrile was substituted in place of 6-[2-(3-Chloro-5-ethyl-4-methoxy-phenyl)-ethyl]-6-cyclopentyl-dihydro-pyran-2,4-dione in that example and 6-Methyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde in place of the 5,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde in that example. 1H NMR (400 MHz, CDCl3) δ: 1.16–1.18 (m, 2H), 1.19–1.5 (m, 8H), 1.51–1.53 (m, 2H), 1.86–1.89 (m, 2H)), 2.16–2.29 (m, 1H), 2.35–2.47 (m, 3H), 2.59 (d, J=17 Hz, 1H), 3.56 (d, J=16 Hz, 1H), 3.65 (d, J=16 Hz, 1H), 7.08 (d, J=7.8, 1 Hz, 1H), 7.20–7.23 (m, 2H), 8.70 (d, J=2.5 Hz, 1H), 9.41 (d, J=2.5, 1.1 Hz, 1H), 10.7 (s, 1H).
