Daim ntawv thov

4-cyanoperidine hydrochloride yog siv los ua kev tshawb fawb.

Kev npaj:

11.9g [75.7mmol] dibutylformamide (99%) tau ntxiv rau 10g [75.7mmol] 4-piperidinium formamide (97%) hauv 50ml n-propyl acetate ncua kev kawm ntawv ntawm 20 degree rau 5 feeb. Tom qab 5 feeb, 18.91g [158.9mmol] ntawm thionyl chloride tau ntxiv rau ntawm 20 degree C. Qhov sib ntxiv yuav siv li 45 feeb, qhov kub ntawm qhov kub ntawm 20 degrees. Tom qab ntxiv, do cov sib tov ntawm 20 ° C rau lwm 18 teev. Lim lub ncua kev kawm ntawv thiab ntxuav lub lim residue nrog n-propyl acetate. Tom qab ziab, 8.55g cov xim tsis muaj xim nyob. Los ntawm kev txheeb xyuas NMR ntau, cov ntsiab lus ntawm 4-cyanoperidine hydrochloride yog 95% (qhov hnyav / hnyav). Cov txiaj ntsig tau suav yog 73% ntawm tus nqi theoretical.
