62119-70-4, 2-Benzofuranacetic acid is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,62119-70-4
Exemplary step 1: benzofuran-2-yl-acetic acid methyl ester (“BFAA methyl ester”) synthesis; Benzofuran-2-yl-acetic acid (BFAA, defined as 1 part by weight; Ix mole fraction) was combined with toluene (approximately 4.3 parts by weight) and methanol (approximately 1.96 parts by weight) was added to form a solution. Concentrated (cone.) hydrochloric acid (approximately 0.28 parts by weight; 0.5x mole fraction) was added while controlling the temperature below about 25 C and the reaction mixture was stirred for several hours. The reaction was quenched with excess aqueous sodium bicarbonate solution. The aqueous layer was separated and the organic layer was washed with aqueous sodium chloride solution. The aqueous layer was separated and the organic product layer was concentrated under vacuum, hi this particular example. Heptane was added to the residue and concentrated under vacuum to yield the product BFAA methyl ester.
As the paragraph descriping shows that 62119-70-4 is playing an increasingly important role.
