2-FLUORO-5-METHYLBENZOICACID Use and Manufacturing

A mixture of SOCI2 (1 mL) was added dropwise to acid 1e (1 1 g) in MeOH (60 mL). The solution was refluxed for 20 h. MeOH was removed on rotovapor, and the residue was dissolved in ether. The organic layer was washed with water, saturated NaHC03, brine, dried over Na2S04, filtered and concentrated to afford clear oil 1f (10.6 g, 88percent yield)General procedure: General Experimental Procedures:[0423]To the flask was added 9 (57 mg, 0.2 mmol) , R-COOH (1.2 eq, 0.24 mmol) , EDCI (58 mg, 0.3 mmol) , DMAP (5 mg, 0.04 mmol) in DCM (5 mL) successively, followed by DIPEA (77 mg, 0.6 mmol) with stirring. The resulting mixture was stirred at room temperature for overnight, and purified by column chromatography to give product.
