반응 단계
The compound was prepared from tert-butyl 7-bromo-5-methyl-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (250 mg, 0.701 mmol) and 4-(4-(trifluoromethyl)benzyloxy)pyridin-2(1H)-one (142 mg, 0.526 mmol) according to the procedure in Example 1 (step c). Purification by flash column chromatography (silica gel, hexanes/EtOAc, 100:0 to 80:20 to 50:50 to 25:75 then 0:100) provided the title compound (73 mg, 19%) as a solid, that contained an impurity: ESI MS m/z 554 [M+H]+.
