Reaction Steps

The title compound was prepared analogously to example A(1) where 6-cyclopentyl-6-{2-[3-ethyl-4-(1,3-oxazol-2-yl)phenyl]ethyl}dihydro-2H-pyran-2,4(3H)-dione (Example A(135)) was substituted in place of 6-cyclopentyl-6-[2-(5-ethyl-4-hydroxy-2-propoxy-phenyl)-ethyl]-dihydro-pyran-2,4-dione in that example and 6-methyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde was substituted in place of 5,7-dimethyl-[1,2,4]triazolo[1,5-a]pyrimidine-2-carbaldehyde.
