合成路线图解说明:

The reaction of methyl acetoacetate (I) with 3,4-difluorobenzaldehyde (II) in hot benzene gives the corresponding benzylidene derivative (III), which is cyclized with O-methylisourea (IV) by means of NaHCO3 in hot DMF yielding the dihydropyrimidine (V). The condensation of (V) with 4-nitrophenyl chloroformate (VI) by means of DMAP in dichloromethane affords the 4-nitrophenyl ester (VII), which is brominated with Br2 in chloroform to the bromomethyl compound (VIII). The cyclization of (VIII) by heating at 130 C affords the furopyrimidine (X), which is treated with propylamine derivative (X) in THF or dichloromethane to furnish the target amide.
