Reaction Steps

3-Isopropyl-8-methyl-5-prenyloxycarbostyril (1.90 g, 6.67 mmol) was suspended in N,N-dimethylaniline (30 ml). The suspension was heated and dissolved while stirring at 202° C. for 2 hours. The reaction system was heated under reduced pressure until condensed. The resultant residue was recrystallized from chloroform-hexane to obtain 1.70 g of the title compound as pale yellow powdery crystals (89.5%).
