実験手順

Trifluoroacetic acid (3.5 ml, 45.23 mmol) was added to a solution of 2-t-butoxycarbonyl-9-methyl-1,2,3,4-tetrahydropyrido[3,4-b]indole (1.848 g, 6.461 mmol) in dichloromethane (25 ml) and stirred at room temperature for 3 hours, diluted with dichloromethane (125 ml), washed with 2M sodium hydroxide (2×50 ml), water and dried (MgSO4). The magnesium sulfate was collected by filtration and the filtrate evaporated in vacuo to give the title product.
