The title compound was prepared analogously to Example A(224) where 5-methyl-[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-ethyl-4-hydroxyphenyl)ethyl]dihydro-2H-pyran-2,4(3H)-dione 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, 3H), 1.30–1.80 (brm, 8H), 2.00–2.40 (brm, 3H), 2.50 (q, J=10.74 Hz 2H), 2.68 (s, 1H), 2.70(s, 2H); 2.92 (m, 2H), 3.69 (m, 3H), 6.64 (d, J=3.56 Hz, 1H), 6.66 (d, J=3.56 Hz, 1H), 7.00 (m, 2H), 8.55 (d, J=6.97 Hz, 1H). Anal. Calcd. For C27H32O4N4: C, 68.05; H, 6.77; N, 11.76. Found: C, 68.24; H, 6.80; N, 11.77.
