Procedure
6-[4-(3,3-Dimethyl-butyryl)-piperazin-1-yl]-N-(3-iodo-4-methyl-phenyl)-nicotinamide was synthesized by the addition 3,3-dimethyl-butyryl chloride (0.055 mmol) to N-(3-iodo-4-methyl-phenyl)-6-piperazin-1-yl-nicotinamide (0.05 mmol) partially dissolved in DCM followed by the addition of TEA and stirred at room temperature over night. The reaction was diluted with ethyl acetate washed with water and brine, dried over sodium sulfate, concentrated and the residue was trirturated with ether and hexanes to afford the product, 6-[4-(3,3-dimethyl-butyryl)-piperazin-1-yl]-N-(3-iodo-4-methyl-phenyl)-nicotinamide. LCMS calcd for C23H29IN4O2 (m/e) 520, obsd 521 (M+H).
