Procedure

To a reaction vial charged with 8-fluoro-4H-thieno[3,2-c]chromene-2-carbonyl chloride (0.05 g, 0.2 mmol) and 2-chloro-N-methylaniline (0.034 g, 0.24 mmol) was added a catalytic amount of DMAP. Pyridine in methylene chloride (1.2 M, 0.66 mL) was added and the reaction was stirred at room temperature with LC/MS monitor. The reaction was complete in a couple hours. After aqueous work up, the reaction was concentrated in vacuo, taken into DMF at 100 mg/ml and purified by preparative RP-HPLC to give 165bp. Yield=28% of theoretical. MS: (ESI+)=374.8
