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 (3 g, 15.87 mmol) and 3-chloro-2-methyl-1-propene (1.58 g, 17.46 mmol). As a result, 3.48 g of the title compound was obtained as pale brown crystals (90.2%).
