실험 절차

Methyl 4-(1-(2-(6-methylpyridin-3-yl)ethyl)hydrazinyl)benzoate (0.1 g, 0.350 mmoles) and 1-methylpiperidin-4-one (0.052 g, 0.350 mmoles) was taken up in 1M HCl (4 mL) and heated at 100° C. for 18 hr. LCMS of the reaction mixture shows the formation of the product. The reaction mixture was concentrated and purified by reverse phase HPLC to give 5 mg of 2-Methyl-5-(2-(6-methylpyridin-3-yl)ethyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole-8-carboxylic acid, as a white solid, 4% yield.
