10.4 g (0.060 mol) of 2-bromophenol, 23.20 g (0.066 mol) of tris(4-methoxyphenyl) phosphine, 0.65 g (5 mmol) of nickel chloride, and 40 ml of ethylene glycol were put into a separable flask (volume, 200 ml) equipped with a condenser and a stirrer, and reacted with stirring under heat at 160° C. The reaction liquid was cooled, 40 ml of pure water was dropwise added thereto, and the deposited crystal was washed with toluene, taken out through filtration, and dried to obtain tris(4-methoxyphenyl)(2-hydroxyphenyl)phosphonium bromide.
