710-18-9, The chemical industry reduces the impact on the environment during synthesis 710-18-9, name is 1-Methoxy-4-(trifluoromethoxy)benzene, I believe this compound will play a more active role in future production and life.
PREPARATION 18 2-Methoxy-5-trifluoromethoxybenzoyl chloride Combine 2-methoxy-5-trifluoromethoxybenzene (1.0 g, 5.2 mmol) and trifluoroacetic acid (200 mL). Add slowly portionwise hexamethylenetetraamine (26 g, 185.7 mmol). Heat at 60 C. After 24 hours, cool to ambient temperature and pour the reaction mixture into a 2M aqueous solution of sulfuric acid (500mL). Cool and extract ten times with diethyl ether. Dry the combined organic layers over Na2 SO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluding with 1/4 ethyl acetate/hexane to give 2-methoxy-5-trifluoromethoxybenzaldehyde.
