実験手順

The compound was prepared from tert-butyl 7-bromo-5-methyl-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (200 mg, 0.548 mmol) and 4-phenethylpyridin-2(1H)-one (109 mg, 0.548 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 (126 mg, 48%) as a yellow solid:
