Procedure

In a sufficiently dried egg-plant type flask provided with a stirrer was sufficiently dried 0.361 g (2 mmol) of 3-tert-butyl-4-hydroxyanisole recrystallized from hexane. After completion of the drying, 3.3 ml of methylene chloride was added thereto. Then, under nitrogen atmosphere, 0.9 ml (1 mmol) of trimethylaluminum was slowly added dropwise with ice-cooling and stirring, and the mixture was mixed in the dark at room temperature for 1 hour to obtain a methylene chloride solution of methylaluminum bis(3-tert-butyl-4-methoxyphenoxide) (1 mmol/3.3 ml).
