Participants

Reaction Steps

Reaction of 5-chloro-1-isopropyl-4-nitro-1H-pyrazole and tert-butyl piperidin-4-ylmethylcarbamate gave tert-butyl (1-(1-isopropyl-4-nitro-1H-pyrazol-5-yl)piperidin-4-yl)methylcarbamate as a pale yellow solid (0.45 g, 92%). 1H NMR (400 MHz, CDCl3) δ 8.06 (s, 1H), 4.78 (hep, J=6.7 Hz, 1H), 4.64 (s, 1H), 3.42-3.29 (m, 2H), 3.11 (t, J=6.6 Hz, 2H), 2.95-2.87 (m, 2H), 2.05 (s, 1H), 1.81 (d, J=12.8 Hz, 2H), 1.46 (s, 9H), 1.43 (d, J=6.7 Hz, 6H), 1.37 (dd, J=12.1, 4.3 Hz, 2H)
