実験手順

Stirred 4-aminopiperidyl 4-{[4-(4-chlorophenyl)pyrimidin-2-yl]amino}phenyl ketone hydrochloride (300 mg, 0.582 mmol) in 10 mL THF with triethylamine (0.293 mg, 2.91 mmol). Acetic anhydride (89 mg, 0.873 mmol) was added and the reaction was stirred for 40 minutes. The solution was concentrated down and purified by preperative HPLC to give N-{1-[(4-{[4-(4-chlorophenyl)pyrimidin-2-yl]amino}phenyl)carbonyl]-4-piperidyl}acetamide (0.120 g, 46% yield): HPLC Retention time; 6.92 min. (Method B) M+1; 450.4
