Embodiment 1
[0102]
[0103] 2'-(tert-butyl)-1-(2-phenylquinoline-4-carbonyl)-2'H-spiro[piperidine-4,5'-pyrano[3,2-c]pyrazole ]-7'(6'H)-one (I 1 )
[0104] The aqueous solution (120 mL) of tert-butylhydrazine hydrochloride (3.74 g, 30 mmol) and glyoxal (4.5 g, 25 mmol) was reacted at room temperature for 2 h; the reaction solution was extracted with dichloromethane, the organic phases were combined, dried over anhydrous sodium sulfate, and then reduced Concentrated under pressure to obtain compound (E)-1-(2-(tert-butyl)hydrazino)propan-2-one. (E)-1-(2-(tert-butyl)hydrazino)propan-2-one (8.8g, 62mmol) and 40% glyoxal solution (25mL, 180mmol) were dissolved in 100mL distilled water, heated to reflux for 5h After cooling to room temperature, the reaction solution was extracted with ethyl acetate, the organic phases were combined, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain the compound 1-tert-butyl-4-hydroxypyrazole-3-ethanone. Dissolve 1-tert-...
