Participants

Reaction Steps

To a solution of 5-(2,4-difluorophenoxy)-1-isobutyl-1H-indazole-6-carboxylic acid (0.050 g, 0.14 mmol), (S)-2-amino-4-piperidin-1-yl-butyric acid methyl ester dihydrochloride (0.043 g, 0.16 mmol), EDCI (0.033 g, 0.17 mmol) and HOBt (0.023 g, 0.17 mmol) in dichloromethane was added dropwise DIEA (0.093 g, 0.72 mmol). The reaction mixture was stirred at room temperature until HPLC analysis showed consumption of the starting material and then was diluted with dichloromethane and washed with saturated NaHCO3. The organic layer was dried over MgSO4 and concentrated under reduced pressure. The residue was chromatographed to afford 0.051 g of product (67% yield).
