反応手順
To a solution of 6-hydroxy-α-methyl-2-naphthaleneacetic acid (10.8 g, 50 mmol) in methanol (100 ml) is added sodium methoxide (100 mmol). After 10 minutes the solvent is removed and replaced with dimethylformamide (250 ml). 2-(Chloromethyl)quinoline (17.8 g, 100 mmol) is then added and the reaction mixture is stirred for 8 days at room temperature. The reaction mixture is partitioned between water and methylene chloride, the organic layer is washed with water and evaporated to yield 27 g of an oil. Recrystallization of this oil twice from acetonitrile gives 10.6 g of white crystals of intermediate ether ester (42% yield, m.p. 106°-108° C.).
