反応手順

Methyl 2-chloro-4-methanesulfonyl-3-dimethoxymethylbenzoate in an amount of 3.0 g (9.3 mmol) was dissolved in methanol in a volume of 30 ml, and to the resulting solution, was added 10% aqueous solution of sodium hydroxide in a volume of 20 ml, and then, the mixture was stirred for 1 hour at an ambient temperature. The reacted-mixture was then added with 1-N hydrochloric acid to make it acidic, and crystals precipitated were filtrated, washed with water and dried to obtain the objective compound in an amount of 2.5 g.
