HCID 574772356-Cyclopentyl-3-(5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-ylmethyl)-6-[2-(3-ethyl-4-hydroxy-phenyl)-ethyl]-4-hydroxy-5,6-dihydro-pyran-2-one

Procedure

The title compound was prepared by coupling 6-Cyclopentyl-6-[2-(3-ethyl-4-hydroxy-phenyl)-ethyl]-dihydro-pyran-2,4-dione (from Example A(22)) to 5,7-Dimethyl-[1,2,4]triazolo[1,5-α]pyrimidine-2-carbaldehyde using the Me2NHBH3 method described in the synthesis of Example B(31).
