3-Chloro-2-hydroxybenzaldehyde CAS 1927-94-2 belongs rau benzene derivatives thiab yuav siv tau los ua intermediates hauv tshuaj thiab tshuaj synthesis
Shandong Ntseeg
Txoj kev npaj: MgCl2 (22.2g, 233.35mmol) thiab triethylamine (59.03g, 583.39mmol) tau ntxiv rau cov tshuaj acetonitrile (200ml) ntawm 2-chlorophenol (20.0g, 155.60mmol) ntawm chav tsev kub. Ntxiv poly (chemicalbook formaldehyde, 0.52g, 1.05mol) rau qhov sib tov, thiab tom qab ntawd reflux rau 4 teev. Qhov sib xyaw ua ke tau txias rau hauv chav tsev kub, quenched nrog 2nhcl, muab rho tawm nrog ether, qhuav nrog MgSO4, lim thiab concentrated nyob rau hauv lub siab txo. Cov khoom siv raw khoom tau ua kom huv los ntawm silica gel kem chromatography kom tau txais lub npe compound 3-chloro-2-hydroxybenzene.
