Procedure: A mixture of N1-(4-bromophenyl)-2-fluorobenzamide (3.3 g, 0.0112 mol) and 2,4-bis-(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (2.27 g, 0.00561 mol) was heated in toluene at reflux under an atmosphere of nitrogen for 3 hours. The reaction mixture was cooled to ambient temperature, the solvent was removed under reduced pressure and the residue was purified by flash chromatography on silica using ethyl acetate/n-heptane (1:6) as mobile phase to yield N1-(4-bromophenyl)-2-fluoro-1-benzenecarbothioamide (3.1 g, 0.010 mol) as a yellow solid. at reflux under an atmosphere of nitrogen for 3 hours the solvent was removed under reduced pressure the residue was purified by flash chromatography on silica

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 2-fluorobenzoyl chloride (5.82 g, 0.0367 mol) and 4-bromoaniline (6.31 g, 0.0367 mol) in anhydrous dichloromethane (150 mL) was cooled to 0° C. and N,N-diisopropylethylamine (5.21 g, 0.0407 mol) was added under nitrogen atmosphere dropwise. The resulting mixture was stirred at ambient temperature for 24 hours, concentrated and the residue partitioned between ethyl acetate (120 mL) and water (100 mL). The organic phase was washed with brine, dried with magnesium sulfate and concentrated. The residue was suspended in cold diethyl ether (50 mL) and the precipitate was collected by filtration and dried to yield N1-(4-bromophenyl)-2-fluorobenzamide (9.6 g, 0.0326 mol) as a white solid. concentrated the residue partitioned between ethyl acetate (120 mL) and water (100 mL) The organic phase was washed with brine dried with magnesium sulfate concentrated the precipitate was collected by filtration dried
