To a stirred suspension of N-(1-Boc-piperidin-3-ylmethyl)-aniline 4 (61.0 mg, 0.21 mmol) and piperidinomethyl polystyrene resin (60 mg) in 0.6 mL of dry CH2Cl2 was added 2-furoyl chloride (95%, 35.1 mg, 1.2 eq.) at room temperature. After being shaken at room temperature for 4 hours, the reaction mixture was passed through an aminopropyl NH2 cartridge and washed with CH2Cl2. Removal of CH2Cl2 afforded furan-2-carboxylic acid N-(1-Boc-piperidin-3-ylmethyl)-N-phenyl amide 13 (75 mg, 93%). LRMS 285 (M−100)+.
