HCID 587623596-Cyclopentyl-3-(5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-ylmethyl)-4-hydroxy-6-[2-(4-hydroxy-3-hydroxymethyl-phenyl)-ethyl]-5,6-dihydro-pyran-2-one

Procedure

The title compound was prepared analogously to Example A(97) where 6-Cyclopentyl-6-[2-(4-hydroxy-3-hydroxymethyl-phenyl)-ethyl]-dihydro-pyran-2,4-dione (Example A(195)) was substituted in place of 2-{4-[2-(2-cyclopentyl-4-hydroxy-6-oxo-3,6-dihydro-2H-pyran-2-yl)ethyl]-2-fluorophenyl}-2-methylpropanenitrile and 5,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde was substituted in place of 2-ethyl-4-methyl-1H-imidazole-5-carbaldehyde from that example. 1H NMR (400 MHz, DMSO-d6): δ 1.34-2.09 (m, 11H) 2.0-2.21 (m, 2H), 2.47-2.74 (m, 10H), 3.74 (d, J=16 Hz, 1H), 3.80 (d, J=16 Hz, 1H), 4.44 (s, 2H), 6.65 (d, J=8 Hz, 1H), 6.88 (d, J=8 Hz, 1H), 7.04 (s, 1H), 7.09 (s, 1H), 9.06 (s, 1H). Anal. Calcd. For C27H32N4O5.H2O: C, 62.96; H, 6.75; N, 10.88. Found: C, 62.97; H, 6.57; N, 10.83. MS (ESI): 493.2 (M+H)+.
