Reaction Steps
3-(2-Bromoethoxy)-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(methylsulfonylmethyl)benzamide (50 mg, 0.095 mmol) was dissolved in DMF (1.0 ml) and treated with potassium carbonate (18 mg, 0.13 mmol) and piperazin-2-one (11 mg, 0.11 mmol) for 18 hours. The reaction was heated for 2.0 hours at 50° C., then additional potassium carbonate (18 mg, 0.13 mmol) and piperazin-2-one (11 mg, 0.11 mmol) was added. After 2 hours, the reaction was quenched in 5% NaOH and extracted with ethyl acetate twice. The ethyl acetate extracts were washed with water once, brine once, dried with MgSO4, and purified by reverse phase HPLC to yield 16 mg of N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(methylsulfonylmethyl)-3-(2-(3-oxopiperazin-1-yl)ethoxy)benzamide. MS (Q1) 558 (M)+.
