How is (2R)-2-Amino-2-(4-bromophenyl)ethanol hydrochloride (CAS: 1916569-82-8) typically synthesized?

(2R)-2-Amino-2-(4-bromophenyl)ethanol hydrochloride can be synthesized by several methods, including reduction of 2-bromo-2-(4-bromophenyl)ethanol to the corresponding alcohol followed by reaction with ammonia to form the amino group. The reaction is typically carried out under mild conditions to avoid over-reduction, and the use of a base like sodium hydroxide can improve the yield. The product is then treated with hydrochloric acid to form the hydrochloride salt.
