Procedure

To a mixture of 2-((S)-1-(2-fluorophenyl)ethylamino)-5-methylthiazol-4(5H)-one (0.0500 g, 0.198 mmol), 4-bromobenzonitrile (Aldrich, 0.0721 g, 0.396 mmol), Pd2(dba)3 (Aldrich, 0.0127 g, 0.0139 mmol), 2-(diphenylphosphino)-1-(2-(diphenylphosphino)naphthalen-1-yl)naphthalene (Strem, 0.0123 g, 0.0198 mmol), and NaN(TMS)2 (Aldrich, 0.0727 g, 0.396 mmol) was added toluene (2 mL) in a dry box. The mixture was gradually heated to 95° C. and stirred overnight. The reaction was cooled to ambient temp. and quenched with NH4Cl (5 mL). The reaction mixture was extract with EtOAc. The organic phase was dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography. MS: 354 (M+1)
