Reaction Steps
A solution of 4-nitrophenyl 4-(pent-4-ynyl)piperazine-1-carboxylate (1.37 g) in THF (10 mL) was treated with 40% aq. MeNH2 (10 mL) at 70 C for 2 h. The mixture was concentrated and diluted with conc. NH4OH (5 mL) and water (15 mL). Extraction (DCM, 80 mL) and concentration gave N-methyl-4-(pent-4-ynyl)piperazine-1-carboxamide (0.659 g).
