Procedure

To a solution of 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (2 g, 11.6 mmol) dissolved in methylene chloride (20 mL) is added 2,2-dimethyl-propionyl chloride (1.42 mL, 11.6 mmol) followed by the addition of triethylamine (1.61 mL, 11.6 mmol). The reaction mixture is stirred at room temperature for 30 minutes The reaction is quenched with water and extracted with methylene chloride three times. The combined organic extracts are washed with saturated sodium bicarbonate, a saturated sodium chloride solution, dried with magnesium sulfate, and concentrated in vacuo to give 2.8 g (94%) of the title compound as a grey solid.
