実験手順
The same procedures as described in Example 8 were carried out by using 4.16 g (25 mM) of 4-isobutylcatechol, 5.06 g (50 mM) of triethylamine and 3.50 g (28 mM) of oxalyl chloride. 6-iso-Butyl-1,4-benzodioxine- 2,3-dione 2/5 hydrate was obtained in the yield of 5.11 g (22.5 mM) as colorless crystals having a melting point of 92°-97° C.
