Reaction Steps

To a solution of 2.10 g (11.0 mmol) of 1-[2-chloroethylcarbamoyl]-2-oxopyrrolidine and 1.40 g (10 mmol) of 4-methoxybenzenethiol in 25 ml of DMF were added 2.47 g (16.5 mmol) of NaI and 3.02 g (22 mmol) of K2CO3, and the mixture was heated at 100° C. for 4.5 hr. The reaction solution was poured into ethyl acetate, washed with water, diluted hydrochloric acid, water, and saturated brine in order. After drying, the solvent was removed by evaporation. The residue was refined by silica gel column chromatography, whereby 2.78 g (94.6%) of the crystalline objective compound (Ia-45) was obtained from the eluate with benzene/ethyl acetate (8/1-5/1 v/v). The needles melting at 64.0°-65.0° C. are obtained by recrystallizing from ether-n-hexane. The properties of the objective compound (Ia-45) are shown in Table 7.
