Diisopropylethylamine → (3R)-3-[(2-Chloro-benzoyl)amino]-N-methyl-N-[1-(2-methylamino-pyrimidin-4-yl)-piperidin-4-yl]-2,3-dihydro-1H-indene-5-carboxylic acid amide

Reaction Steps

A mixture of (R)-3-(2-chlorobenzamido)-N-methyl-N-(piperidin-4-yl)-2,3-dihydro-1H-indene-5-carboxamide (400 mg, 0.973 mmol, 1 eq), (4-chloropyrimidin-2-yl)methylamine (280 mg, 1.946 mmol, 2 eq) and DIPEA (0.33 ml, 1.946 mmol, 2 eq) in dioxane (10 ml) was refluxed for 16 h. When the reaction was complete according to TLC monitoring, concentration under reduced pressure was carried out and the residue was taken up in dichloromethane (100 ml) and washed with water (40 ml) and saturated sodium chloride solution (40 ml). The organic phase was dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by column chromatography (silica gel, 6% methanol in dichloromethane). The desired product was in the form of a white solid. Yield: 49% (250 mg, 0.482 mmol)
