実験手順

3-Bromo-4-hydroxybenzyl alcohol (1.22 g, 6.0 mmol) prepared from i) and sodium methoxide (0.36 g, 6.6 mmol) as base were added to N,N-dimethylformamide (100 ml), and the mixture was stirred for 30 min at room temperature. Chloromethyl resin (Merrifield resin, 1 mmol of chloromethyl site, formula 4; 1.22 g, 2.0 mmol) was added to the reaction solution and stirred for 24 hr at 50° C. The same was filtrated and washed repeatedly with water, methanol and dichloromethane. IR and XPS analyses were performed.
