Paragraph 0057; 0058; 0059, (2019/05/08)
The invention discloses a preparation method of p-(2-methoxyl) ethyl phenol. According to the preparation method, p-chlorophenol is taken as the raw material, after etherification reactions, p-chlorophenol with a protected phenolic hydroxyl group is obtained, and after Grignard reactions, chlorination reactions, and methoxyl substitution reactions, p-(2-methoxyl)ethyl phenol is generated. The provided preparation method has the advantages of easily available raw materials, mild reaction conditions, high safety coefficient, strong operability, simple technology, easy industrialization, high product purity, and stable quality. The prepared p-(2-methoxyl)ethyl phenol totally meets the using requirements of medical intermediates.

A new tert-butylating reagent, 2,4,6-tris(tert-butoxy)-1,3,5-triazine (TriAT-tBu) has been developed for the acid-catalyzed tert-butylation of alcohols and carboxylic acids. The reaction of various alcohols and carboxylic acids with TriAT-tBu in the presence of a catalytic amount of an acid provided the corresponding tert-butyl ethers and esters in good to high yields. TriAT-tBu is an air-stable solid synthesized in good yield from inexpensive starting materials, namely, cyanuric chloride, tBuOH, and sodium hydride.
