실험 절차

18.3 g of 2-methoxymethyl-4-nitrophenol (1) (0.1 mol), 8.3 g (0.06 mol) of potassium carbonate and 40 ml of dimethylformamide were heated on a boiling water bath, and 12.1 ml (0.105 mol) of benzyl chloride were added over 10 minutes. After heating for 1 hour on the boiling water bath, the mixture was poured onto 150 g of ice. The yellow-brown crystals formed were filtered off, reslurried in ice-cold water and washed with petroleum ether. The wet product was recrystallized from 75 ml of isopropanol to give, after drying, 21 g of expected product with a melting point of 108° C. The results of the elementary analyses were as follows:
