Procedure
The title compound was prepared by the method of Example 90 from tert-butyl(±)-cis-2-bromo-4,5,7,8,10,10a-hexahydropyrido[4,3-b]pyrrolo[3,2,1-hi]indole-9(6aH)-carboxylate (124 mg, 0.27 mmol) and corresponding 2,3-dichlorophenylboronic acid (104 mg, 0.54 mmol), to afford after chromatographic purification the title compound (157 mg, 99%) as a white amorphous solid. 1H NMR (CDCl3, 300 MHz) δ 7.30–7.40 (m, 1H), 7.20 (s, 1H), 7.18 (d, 1H, J=3.6 Hz), 6.99 (s, 1H), 6.94 (s, 1H), 3.80–3.90 (m, 1H), 3.60–3.80 (m, 1H), 3.10–3.50 (m, 7H), 2.80–3.00 (m, 1H), 1.70–1.90 (m, 2H), 1.47 (s, 9H) ppm. MS (CI, NH3): 445 (base, M+H).
