実験手順
HATU (168 mg, 0.44 mmol, 1 eq) and DIPEA (200 μl, 1.1 mmol, 2.5 eq) were added to an ice-cooled solution of 3,3,3-trifluoropropionic acid (67.5 mg, 0.528 mmol, 1.2 eq) in THF (5 ml), and the mixture was stirred for 30 min. (R)-3-Amino-N-methyl-N-(1-(pyridin-4-yl)piperidin-4-yl)-2,3-dihydro-1H-indene-5-carboxamide (154 mg, 0.44 mmol, 1 eq) was dissolved in THF (2 ml) and added dropwise to the reaction solution, and stirring was carried out for 16 h at RT. The reaction solution was diluted with dichloromethane (100 ml), washed with sat. sodium hydrogen carbonate solution (40 ml), sat. ammonium chloride solution (40 ml), water (40 ml) and sat. NaCl solution (40 ml), dried over sodium sulfate and concentrated under reduced pressure. After purification by column chromatography (silica gel, 5% MeOH in dichloromethane), the desired product was obtained in the form of a white solid. Yield: 59% (120 mg, 0.26 mmol).
