반응 단계

2.0 g of 1,2,3,9-tetrahydro-9-methyl-4H-carbazol-4-one, 1.65 g of 2-methyl imidazole and 2.74 g of dipiperidinomethane were suspended in 20 ml of N,N-dimethylformamide, and then 4 ml of chlorotrimethylsilane was slowly added thereto. The reaction mixture was stirred for 8 hours at 90° C. 100 ml of water was added to the reaction mixture. The resulting solid was filtered and dried, which was then suspended in acetone and stirred for 3 hours, and then filtered and dried under a reduced pressure to give 1.99 g of title compound (yield 68%).
