tert-Butyl piperazine-1-carboxylate → HCID 66878672, compound

Participants

Reaction Steps

Procedure F was performed using 80 mg of 6-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-2-methylnicotinamide and 209 mg of 1-Boc-piperizine in 1 mL of BuOH. The reaction mixture was evaporated to afford tert-butyl 4-(5-(4-chloro-3-(pyridin-2-yl)phenylcarbamoyl)-6-methylpyridin-2-yl)piperazine-1-carboxylate. 150 mg of tert-butyl 4-(5-(4-chloro-3-(pyridin-2-yl)phenylcarbamoyl)-6-methylpyridin-2-yl)piperazine-1-carboxylate was treated with TFA (1 mL) containing trace amounts of H2O for 2 h. The reaction mixture was diluted with ethyl acetate, washed with 0.1N sodium hydroxide and brine, dried (MgSO4) and evaporated. Purified by reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-yl)phenyl)-2-methyl-6-(piperazin-1-yl)nicotinamide. MS (Q1) 408.3 (M)+.
