Procedure
To 6-allyloxy-8-methylcarbostyril (10.11 (47.0 mmol)), N,N-dimethylaniline (25 ml) was added, and the mixture was stirred in a bath of 200° C. for 11 hours. Subsequently, the mixture was cooled. n-Hexane was added to the cooled mixture. The precipitated crystals were collected by filtration, and were washed with chloroform. The washed material was subjected to a recrystallizing procedure (chloroform--methanol--n-hexane) to obtain 9.36 g of 5-allyl-6-hydroxy-8-methylcarbostyril as colorless needles (92.6%).
