Potassium Carbonate → 3-Fluoro-2-(3-fluoropyrrolidin-1-yl)benzaldehyde

Participants

Reaction Steps

2,3-Difluorobenzaldehyde (1.0 g, 7.037 mmol) was taken up in dry dioxane (20 ml) in a tube and (S)-3-fluoropyrrolidine (627.1 mg, 7.037 mmol) and K2CO3 (676.4 mg, 10.56 mmol) were added and the mixture refluxed overnight. The reaction mixture was diluted with ethyl acetate, filtered, concentrated to dryness and purified on an ISCO system eluting with Hexane/ethyl acetate (10-100) to give 400 mg of 3-fluoro-2-(3-fluoropyrrolidin-1-yl) benzaldehyde.
