Reaction Steps

Trichloromethyl 2-(4-(3-methoxybenzamido)-2-(1-methyl-1H-pyrazol-5-yl)phenoxy)ethylcarbamate (50.0 g, 94.74 mmol), 4-nitrophenol (14.50 g, 1.1 eq) and magnesium oxide (1.067 mL, 1.0 eq) were taken up in 2 mL of ethyl acetate in a round bottomed flask and stirred at 22° C. for 3 hr. The magnesium oxide was filtered off. The solvent was then evaporated and it was purified by HPLC. The proper fractions were collected and lyophilized to afford the title compound as a white solid in 39.1% yield. LCMS m/z (%)=532 (M+H, 100).
