Reaction Steps
A mixture of dimethyl 5-(pyrrol-1-yl)isophthalate (3.0 g), methyl acetate (0.86 g) and sodium methoxide (0.81 g) in N,N-dimethylformamide (21 ml) was heated at 55° C. for 3 hours. After being cooled to room temperature, the reaction mixture was poured into water (100 ml) and the whole was adjusted to pH 3 with 10% hydrochloric acid. The resulting precipitate was collected and washed with water. This crude product was purified by column chromatography on silica gel (150 ml) with benzene-ethyl acetate (30:1) as an eluent. The fractions containing the object product were collected and evaporated in vacuo. The residue was recrystallized from methanol to afford methyl 3-[3-methoxycarbonyl-5-(pyrrol-1-yl)phenyl]-3-oxopropionate (0.31 g).
