693287-79-5, tert-Butyl 2-(tetrahydro-2H-pyran-4-yl)hydrazinecarboxylate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,693287-79-5
A mixture of tert-butyl 2-(tetrahydro-2H-pyran-4-yl)hydrazinecarboxylate (3.8 g,0.018 mol) and trifluoroacetic acid (20 mL, 0.3 mol) were stirred in dichloromethane (20 mL) for 90 minutes. The mixture was concentrated, and the residue was taken up in acetonitrile (30 mL). l-(2,6-difluoropyridin-3-yl)propan-l-one (2.34 g, 0.0137 mol) was then added, and the resulting mixture was stirred at 75 0C for 72 hours. After cooling to room temperature, the mixture was concentrated, and the residue was purified by flash chromatography on silica gel using a 10-50% hexane:ethyl acetate gradient (flow rate 20 mL/min). The organics were combined and the crude product was then extracted with ethyl acetate. The combined extracts were washed with saturated sodium bicarbonate and then concentrated to afford 2.86 g (83.9 %) of 3-ethyl-6-fIuoro-l-(tetrahydro-2H-pyran- 4-yl)-lH-pyrazolo[3,4-b]pyridine as a white solid. LC/MS (EI) tR 3.5 (Method E), m/z 250 (M++1).
As the paragraph descriping shows that 693287-79-5 is playing an increasingly important role.
