실험 절차

To a solution of 4-((5-bromo-1-tert-butyl-1H-pyrazol-4-yl)methyl)-1-(tert-butoxycarbonyl)piperidine-4-carboxylic acid (241 mg, 0.54 mmol) in toluene (10 mL) was added triethylamine (91 μL, 0.65 mmol) and diphenylphosphoryl azide (0.14 mL, 0.65 mmol). The mixture was heated at 120° C. for 3 hours, the reaction was cooled and the volatiles were removed under reduced pressure. The resultant oil was purified by flash chromatography (25 g silica, 7-60% ethyl acetate/heptane gradient) to yield 225 mg of tert-butyl 4-((5-bromo-1-tert-butyl-1H-pyrazol-4-yl)methyl)-4-isocyanatopiperidine-1-carboxylate as a clear oil. +APCI (M+H) 385.1; 1H NMR (400 MHz, CDCl3, δ): 7.40 (s, 1H), 4.03 (br. s., 2H), 2.97 (br. t, J=12.3, 12.3 Hz, 2H), 2.70 (s, 2H), 1.74 (s, 9H), 1.67 (m, 2H), 1.62 (m, 2H), 1.46 (s, 9H).
