To a stirred solution of 12 mg (0.049 mmol) of 4-(2-(3,3-Difluoropyrrolidin-1-yl)-1-methyl-2-oxoethyl)piperazine (TEA salt), and 20 mg (0.049 mmol) of 4-({(2S,5R)-1-(tert-butoxycarbonyl)-5-[(R)-hydroxy(phenyl)methyl]pyrrolidin-2-yl}methyl)benzoic acid (i-1) in 1 mL anhydrous N,N-dimethylformamide under nitrogen atmosphere was added 0.042 mL (0.24 mmol) of N,N-diisopropylethylamine and 37 mg (0.097 mmol) of 2-(1H-7-azabezotriazole-1-yl)-1,1,3,3,-tetramethyl uranium hexafluoro phosphate methanium. The resulting reaction mixture was stirred at ambient temperature overnight. The reaction was purified by reverse-phase HPLC (TMC Pro-Pac C18; 10-100% 0.1% trifluoroacetic acid in acetonitrile/0.1% trifluoroacetic acid in water gradient) to give 23 mg of the title compound. LC/MS: (M+1)=641.2.
