Participants

Reaction Steps

Reaction, past-process, and recrystallization (chloroform-methanol-ether) were performed in a manner similar to that described in Example 277 using 6-(2-methyl-2-propenyl)-5-hydroxy-3,8-dimethylcarbostyril (3.29 g, 13.54 mmol) and N-bromsuccinimide (2.41 g, 13.54 mmol).
