실험 절차

N,N′-Disuccinimidyl carbonate (462 mg, 1.2 eq) was dissolved in 30 mL dimethylformamide and cooled to 0° C. To this was added the tert-butyl 2-(4-amino-2-(1-methyl-1H-pyrazol-5-yl)phenoxy)ethylcarbamate (500 mg, 1.81 mmol) dissolved in 10 mL dimethylformamide, drop-wise over 30 mins. The solution was removed from the ice bath and stirred at room temperature for 2 hr, then moved to an oil bath and stirred at 65° C. for 30 minutes. It was then removed from heating and allowed to cool to room temperature. It was used in the following step without purification. LCMS m/z (%)=474 (M+H, 100).
