17. 9-p-Alkoxybenzylcarbazoles (1a-d) were synthesized as follows: Matrix equation presented
18. 2 gave 2 and 3-p-methoxybenzylcarbazole (7) in 14 and 66% yields, respectively. However, when 9-benzylcarbazole was treated with hot TFA for 3 h, the starting material was recovered. Matrix equation presented
19. 2 = 4 : 1) to give 2 (26 mg, 79%), 3a (13 mg, 48%), and 1a (3 mg, 5%).
