α-(2-Bromoethyl)-α-phenylbenzeneacetic acid Use and Manufacturing

Methods of Manufacturing

Brominated with benzylacetonitrile with bromine to produce α-bromobenzeneacetonitrile, which is then condensed with benzene with the participation of anhydrous aluminum trichloride to obtain diphenylacetonitrile, which is combined with ethylene oxide under the action of sodium amide The reaction produces 2, 2-diphenyl-γ-butyrolactone, and finally reacts with hydrogen bromide acetic acid solution at room temperature to obtain the product.

Uses

Loperamide intermediate.
