반응 단계
To a solution of tert-butyl-3-iodobenzylcarbamate (550 mg, 1.65 mmol) in Dioxane (1.2 mL) and DMSO (1.2 mL) was added CuI (16 mg, 0.083 mmol), (1S,2S)—N1,N2-dimethylcyclohexane-1,2-diamine (0.052 ml, 0.33 mmol), pyrazole (135 mg, 1.98 mmol) and K2CO3 (479 mg, 3.47 mmol). After stirring at 120° C. for 3 h, it was concentrated and the residue was purified by column chromatography to give tert-butyl-3-(1H-pyrazol-1-yl)benzylcarbamate (317 mg).
