実験手順
Reaction, post-treatment, and recrystallization (chloroform-n-hexane) were performed in a manner similar to that described in Reference Example 31 using 5-hydroxy-3,8-dimethylcarbostyril (1.4 g, 7.41 mmol) and 4-bromo-2-methyl-2-butene (1.21 g, 8.15 mmol). As a result, 1.41 g of the title compound was obtained as colorless crystals (74.1%).
