Reaction Steps

To a solution of (S,E)-N-(1-((5-(2-chloro-4-(propylamino)pyrimidin-5-yl)-4-pentyn-1-yl)amino)-1-oxopropan-2-yl)-4-(dimethylamino)-N-methyl-2-butenamide (L4, 20 mg) and 3-chloroaniline (28 mg) in tetrahydrofuran (3 mL), (1S)-(+)-10-camphorsulfonic acid (52 mg) was added at room temperature, and the mixture was stirred at 70° C. for 2 hours. The reaction mixture was cooled to room temperature, and then diethylamine was added until the mixture became basic. The solvent was evaporated under reduced pressure, and the obtained residue was purified by basic silica gel column chromatography to obtain (S,E)-N-(1-((5-(2-((3-chlorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)-4-pentyn-1-yl)amino)-1-oxopropan-2-yl)-4-(dimethylamino)-N-methyl-2-butenamide (12-2, 4 mg).
