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 (120mL) of tert-butylhydrazine hydrochloride (3.74g, 30mmol) and methylglyoxal (4.5g, 25mmol) was reacted at room temperature for 2h; Concentrate under reduced pressure to obtain compound (E)-1-(2-(tert-butyl)hydrazino)propan-2-one. Dissolve (E)-1-(2-(tert-butyl)hydrazino)propan-2-one (8.8g, 62mmol) and 40% glyoxal solution (25mL, 180mmol) in 100mL distilled water, and heat 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-butyl-4-hydroxypyrazole-3-ethanone (4.4g, 24mmol), tetrahydropyrrole (568mg, 8mmol), N-BOC-piperidone (5.54g, 28mmol) in 45mL methanol The sol...
