Procedure

To a solution of 5-chloro-4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-2-furancarboxylic acid (200 mg, 0.77 mmol)[prepared according to the procedure of Preparation 6], 2-[(2S)-2-amino-3-(2,4-difluorophenyl)propyl]-1H-isoindole-1,3(2H)-dione (254 mg, 0.80 mmol) and N,N-diisopropylethylamine (0.40 ml, 2.30 mmol) in DCM (10 ml) was added bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (536 mg, 1.15 mmol). After stirring at ambient temperature for 20 hrs, the mixture was concentrated and purified with silica gel column eluting with gradient (0-50% ethyl acetate/hexanes) to afford the title compounds as an off-white foamy solid (304 mg, 0.54 mmol, 71% yield): LCMS (ES) m/e 560(M+H)+.
