A solution of 1-(4-nitrophenyl)piperidine-4-carboxylic acid, (CH3)2NH (2.37 g, 29.06 mmol), HATU (11.05 g, 29.06 mmol) and DIPEA (7.51 g, 58.12 mmol) in 30 mL of THF, was stirred at room temperature overnight. The mixture was added to 20 mL of water, extracted with EA, washed with water and brine, dried over Na2SO4. The volatiles were removed in vacuo to give 4.2 g of N,N-dimethyl-1-(4-nitrophenyl)piperidine-4-carboxamide. MS (m/z)=278 (M+H)+.
