Participants

Reaction Steps

The title compound was prepared by the method of Example 90 tert-butyl(±)-cis-2-bromo-4,5,7,8,10,10a-hexahydropyrido[4,3-b]pyrrolo[3,2,1-hi]indole-9(6aH)-carboxylate (125 mg, 0.28 mmol) and corresponding 3-fluorophenylboronic acid (77 mg, 0.56 mmol), to afford after chromatographic purification the title compound (48 mg, 44%) as a white amorphous solid. 1H NMR (CDCl3, 300 MHz) δ 7.20–7.40 (m, 2H), 7.10–7.20 (m, 3H), 6.80–7.00 (m, 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), 1.48 (s, 9H) ppm. MS (CI, NH3): 395 (base, M+H).
