実験手順

10-Methoxyharmalan (646 mg, 3 mmol) is dissolved in dry dichloromethane (40 ml). Triethylamine (1 ml, 7.2 mmol) and then, dropwise, mesyl chloride (0.25 ml, 3.2 mmol) are successively added with stirring at room temperature under a nitrogen atmosphere. The mixture is stirred for 4 hours at room temperature. Subsequently, after removal of the dichloromethane, the residue is subjected to flash chromatography on a silica column (AcOEt/PE, 50/50). 1-Methylene-2-mesyl-6-methoxy-1,2,3,4-tetrahydro-β-carboline is thus obtained (350 mg, Y=40%).
