Ib txoj hauv kev tshiab
ib). Siv m-difluorobenzene ua cov khoom pib, nws ua rau Friedel-Crafts alkylation cov tshuaj tiv thaiv nrog ethylene oxide nyob rau hauv catalysis ntawm Lewis acid los npaj cov khoom nruab nrab 2,4 ‑ difluorophenethyl cawv;
b). Kauj ruam a) Cov khoom lag luam raug ncaj qha rau cov kauj ruam thib ob uas tsis muaj kev sib cais thiab ua kom huv rau oxidize 2,4 ‑ difluorophenylethanol los tsim 2,4 ‑ difluorophenylacetic acid;
c) Kauj ruam b) Cov khoom 2,4-difluorophenylacetic acid reacts nrog thionyl chloride thiab ammonia los npaj 2,4-difluorophenylacetamide;
d). Kauj ruam c) Cov khoom 2,4-difluorobenzeneacetamide reacts nrog sodium hypochlorite aqueous solution nyob rau hauv induction ntawm bromine, thiab Hoffman degradation tshwm sim los npaj lub hom phiaj khoom 2,4-difluorobenzylamine
