Participants

Reaction Steps

The title compound was prepared from 2-iodoaniline (5.0 g, 22.83 mmol), 4-chlorophenylboronic acid (3.57 g, 22.8 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (II) complex with dichloromethane (0.373 g, 0.46 mmol), and a 5.0 M sodium hydroxide solution (9.1 mL, 45.65 mmol) according to the procedure and in the same manner as described in Example 60, step a. The crude product was purified by flash column chromatography on silica gel, eluting with a mixture of ethyl acetate-hexane (1:12) to yield 4′-chloro-1,1′-biphenyl-2-amine (3.67 g, 18.0 mmol, 79%) as an orange oil;
