Synthetic Route of 37622-90-5<\/a>, These common heterocyclic compound, 37622-90-5, name is Ethyl 4-pyrazolecarboxylate, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

To a suspension of LiAlH4 (5.3 g) in dry THF (100 mL) in a round-bottomed flask, under inert atmosphere (N2), was added portionwise ethyl pyrazole-4-carboxylate (10.0 g) at rt. The reaction mixture was stirred at rt overnight and then poured into a sat. aq. Rochelle salt solution. The mixture was stirred at rt for 3 h and diluted with EA. The layers were separated and the aq. layer was extracted with EA (3x). The combined org. layers were dried over MgS04, filtered and concentrated under reduced pressure. The title compound was obtained, after drying, as a white solid (5.2 g; 76percent yield).1H NMR (d6-DMSO) delta: 12.60 (s, 1H); 7.50 (s, 2H); 4.77 (br. s, 1H); 4.38 (br. s, 2H).<\/p>\n
