反応手順

Commercially available ethyl 1-isopropyl-1H-pyrazole-3-carboxylate was dissolved in diethyl ether, the solution was cooled to 0° C., and a 1M lithium aluminum solution in tetrahydrofuran was added. After stirring for 3 hours, the reaction mixture was poured into a cold 30% aqueous Rochelle's salt solution and was allowed to stir for one hour. The resulting mixture was extracted twice with diethyl ether. The combined organic extracts were washed with 10% aqueous potassium carbonate solution and brine, dried over sodium sulfate, and concentrated under reduced pressure to yield the desired compound (54% yield).
