Participants

Reaction Steps

A mixture of 2-(1-piperazinyl)-4-(4-fluorophenyl)-6,7-dihydro-5H-cyclopentapyrimidine (1.0 g), 2-furoic acid (0.38 g), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.79 g) and chloroform (40 ml) is stirred at room temperature for 2 hours. The reaction mixture is washed with water, dried over anhydrous sodium sulfate, and the solvent is distilled off under reduced pressure. The residue is dissolved in toluene, and the solution is subjected to silica gel column chromatography. The fractions eluted with toluene-ethyl acetate (9 : 1) are collected, and the product therefrom is recrystallized from ethanol to give the desired compound (0.62 g), m.p. 124°-125° C. (ethanol).
