Reaction Steps

(2S,4R)-N-(4-Chloro-phenyl)-N-{2-methyl-1-[4-(3-piperazin-1-yl-propoxy)-benzoyl]-1,2,3,4-tetrahydro-quinolin-4-yl}-acetamide (168 mg) was dissolved in CH2Cl2 (2 mL). Acetic chloride (47 mg) and DIEA (52 uL) were added. The reaction mixture was stirred at room temperature overnight. The organic phase was washed with sat. NaHCO3 (2×5 mL), dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography (EtOAc) to afford pure (2S,4R)-N-(1-{4-[3-(4-acetyl-piperazin-1-yl)-propoxy]-benzoyl}-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl)-N-(4-chloro-phenyl)-acetamide (100 mg, 57%).
