Reaction Steps

C-(1-Benzo[1,3]dioxol-5-yl-cyclopentyl)-methylamine (43.8 mg, 0.200 mmol) and benzofuran-2-carbonyl chloride (36.1 mg, 0.200 mmol) were dissolved in 2 mL of 1,4-dioxane containing triethylamine (83.6 μL, 0.600 mmol). The reaction mixture was stirred for 15 hours, evaporated to dryness, and purified by reverse phase preparative liquid chromatography to yield the pure product (13.0 mg, 0.0358 mmol, 17.8%). ESI-MS m/z calc. 363.2, found 364.2 (M+1)+. Retention time of 4.22 minutes.
