실험 절차

A soluton of (±) 2-(2-chloro-α-hydroxybenzyl)furan [prepared as described in (j) above] (31.3 g.) in dimethylformamide (100 ml.) was treated with sodium hydride (4.1 g.) with ice cooling. Methyl iodide (28.4 g.) was added to the stirred solution over 15 minutes at 15°-30° C. with ice cooling and the mixture was allowed to stand at ambient temperature for 1 hour. The mixture was then diluted with diethyl ether (300 ml.) and filtered. The filtrate was washed with water (3 × 500 ml.), dried over sodium sulphate and evaporated to give a light red oil, which was distilled to give (±) 2-(2-chloro-α-methoxybenzyl)furan (30 g.), b.p. 115° C./0.1 mm.Hg.
