To a solution of the 1-(3,4-methylenedioxyphenyl)-2,3,4,9-tetrahydro-1H-β-carboline (prepared according to the process as disclosed in WO97/43287, Intermediate 7, page 24) (7.37 g, 25 mmol) in dry DMF (25 mL) was added triethylamine (3.52 mL, 25 mmol) and benzyl bromide (3.00 mL, 25 mmol). The mixture was stirred at ambient temperature overnight and added dropwise to a solution of sodium hydroxide (25 mmol) in water (200 mL). A precipitate was formed, collected by vacuum filtration, washed with water (2×50 mL), and dried in vacuo overnight to yield the product as a freely flowing pale yellow powder.
