Pyridine → HCID 67112407, compound

Participants

Reaction Steps

A solution of cyclopropanecarbonyl chloride (Aldrich, 448 mg, 4.31 mmol) in 5 mL of methylene chloride was slowly added over 5 minutes to N-(4-(4-aminobenzoyl)phenyl)-4-fluorobenzamide (1.2 g, 3.59 mmol) in 20 mL of methylene chloride containing 3 mL of pyridine. The reaction was stirred at room temperature for 12 h then quenched with 40 mL of water. The layers were separated and the aqueous layer was extracted with ethyl acetate (2×50 mL). The combined organics were washed with 0.5 N HCl (100 mL), brine (100 mL), dried over sodium sulphate, and filtered. Concentration of the organics provided N-(4-(4-(cyclopropanecarboxamido)benzoyl)phenyl)-4-fluorobenzamide (1.3 g, 3.23 mmol) as a tan solid which was used without further purification.
