Reaction Steps

The title compound was prepared analogously to Example A(224) where 5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde was used in place of 6-methyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde and 6-cyclopentyl-6-[2-(3,5-diethyl-4-hydroxyphenyl)ethyl]dihydro-2H-pyran-2,4(3H)-dione (Example A(235)) was used in place of 6-cyclopentyl-6-{2-[4-hydroxy-3-(2,2,2-trifluoroethyl)phenyl]ethyl}dihydro-2H-pyran-2,4(3H)-dione in that example. 1H NMR (DMSO): δ 1.15 (t, J=7.54 Hz, 6H), 1.30–1.80 (brm, 8H), 2.00–2.20 (brm, 5H), 2.43 (q, J=19.06 Hz 4H), 2.60 (s, 3H), 2.80 (brm, 7H), 3.34 (m, 3H), 6.70 (s, 2H), 6.99 (s, 1H). Anal. Calcd. For C30H38O4N4, C, 69.47; H, 7.38; N, 10.80. Found: C, 69.45; H, 7.35; N, 10.75.
