L-Tartaric acid → 1-{4-Fluoro-5-(2-fluoropyridin-3-yl)-1-[(5-fluoropyridin-3-yl)sulfonyl]-1H-pyrrol-3-yl}-N-methylmethanamine L-tartrate

Participants

Reaction Steps

A solution of L-tartaric acid (59 mg) in ethanol (4 mL) was added to 1-{4-fluoro-5-(2-fluoropyridin-3-yl)-1-[(5-fluoropyridin-3-yl)sulfonyl]-1H-pyrrol-3-yl}-N-methylmethanamine (150 mg), and the mixture was concentrated under reduced pressure. The residue was recrystallized from ethanol to give the title compound as a white solid (yield 184 mg, 88%).
