Participants

Reaction Steps

To 100 mg of 7-benzyloxycarbonyl-2-[4-(4-quinolin-2-ylpiperazin-1-yl)butyl]-3,4,5,6,7,8-hexahydro-4-oxa-9-thia-1,3,7-triaza-9H-fluorene as synthesized in Example 3-14, 5 ml of hydrogen bromide-acetic acid solution was added and stirred at room temperature. After neutralizing the system with saturated aqueous sodium hydrogencarbonate solution, the reaction product was extracted with chloroform, dried over anhydrous magnesium sulfate and concentrated to provide 78 mg (100%) of 2-[4-(4-quinolin-2-ylpiperazin-1-yl)butyl]-3,4,5,6,7,8-hexahydro-4-oxa-9-thia-1,3,7-triaza-9H-fluorene.
