Reaction Steps

To a mixture of 20 mg of 3-((4-(piperidin-1-yl)-2-(4-((3-(trifluoromethyl)-benzyl)carbamoyl)pyridin-2-yl)phenyl)carbamoyl)benzoic acid 4.1e, 28 mg of diisopropylethylamine, and 6.5 mg of ethyl 2-(piperidin-4-yl)acetate in 1 mL of DMF was added 17 mg of HATU. The mixture was stirred at 60° C. for 1 h. The solution was diluted with water and extracted with ethyl acetate. The organic phase was washed with water, then brine. It was dried and the solvent was evaporated at reduced pressure. It was dissolved in 4:1 methanol/water and treated with 19.4 mg of LiOH.H2O. After stirring for 20 h the product was isolated by reverse phase HPLC, eluting with 0.5% TFA in a gradient of water and acetonitrile to give 10.9 mg of product. MS (ES, m/z): 728.7 [M+H]+.
