Reaction Steps

To a solution of 1-(1-methylethyl)-3-methyl-1H-pyrazole-4-carboxylic acid (2.00 g, 11.9 mmol) in benzene (15.9 mL) and methanol (7.93 mL) at room temperature was added 2M trimethylsilyldiazomethane (23.8 mL). The resulting solution was stirred at room temperature for 3 hours. Solvent was removed at reduced pressure on a rotary evaporator to yield the title compound (2.17 g, 111.89 mmol, 100% yield) as a white solid.
