Reaktionsschritte

To a solution cooled (0° C.) of 2-(1H-pyrazol-4-yl)ethanol (93 g, 0.83 mol) and potassium hydroxide (48.8 g, 0.87 mol) in absolute ethanol (9.25 L) was added methyl iodide (178 g, 1.25 mol) dropwise. The mixture was allowed to react for 30 min, at which time it was poured into water (400 mL) and extracted with diethyl ether (4×100 mL). The combined organic layers were dried (Na2SO4), filtered, concentrated in vacuo, and purified by vacuum distillation to afford the title compound.
