合成路线1
该中间体在本合成路线中的序号：(II)Esterification of ethanolamine hydrochloride (I) by means of acetyl chloride in HOAc yields 2-aminoethyl acetate (II). The carboxyl groups of folic acid (III) are protected by coupling with amino ester (II) in the presence of EDC, to produce diamide (IV). Subsequent condensation of (IV)with dimethylformamide diethylacetal (DMF-DEA) gives formamidine (V). The 4-carbonyl group of (V) is then protected as the phenethyl ether (VII) by treatment with 4-nitrophenethyl alcohol (VI) under Mitsunobu coupling conditions.
