実験手順

To a solution of tert-butyl 6-amino-1,3,4,5-tetrahydro-2H-pyrido[4,3-b]indole-2-carboxylate (4.62 g, 16.08 mmol) in benzene (100 mL) was added a catalytic amount of DMAP. An inert atmosphere was created and chloropropionyl chloride (2)(1.68 mL) was added dropwise to the reaction mixture. After stirring at room temperature for 20 min, the reaction mixture was transferred to a separatory funnel containing 50% solution of sodium bicarbonate and was extracted with CH2Cl2 (3×250 mL). The combined organics were dried over Na2SO4 and concentrated in vacuo to give tert-butyl 6-[(3-chloropropanoyl)amino]-1,3,4,5-tetrahydro-2H-pyrido[4,3-b]indole-2-carboxylate as a white solid in 99% yield: 1H NMR (DMSO, 500 MHz) δ 1.38–1.53 (m, 9H), 2.75–2.99 (m, 2H), 3.65–3.78 (m, 4H), 3.88–3.97 (m, 2H), 4.53 (brs, 2H), 6.88–6.96 (m, 1H), 7.15–7.22 (m, 1H), 7.31–7.37 (m, 1H), 9.72 (brs, 1H), 10.44 (brs, 1H) ppm.
