Reaction Steps

To a solution of tert-butyl 3-(5-amino-1H-indol-3-yl)cyclohexyl(ethyl)carbamate (0.62 g, 1.73 mmol) in dry EtOH (25 mL) was added methyl thiophene-2-carbimidothioate hydroiodide (1.00 g, 3.47 mmol) and the reaction left to stir at room temperature for 48 hours. The solvent then was evaporated and the mixture dissolved in dichloromethane (20 mL) and washed with 2N NaOH (10 mL). The organic layer was extracted and evaporated. The crude was purified on column chromatography (2 M NH3 in MeOH:CH2Cl2, 2:98 to 5:95) to give the title compound as a yellow solid (0.80 g, quantitative). 1H-NMR (DMSO-d6) δ 1.04 (t, 3H, J=6.9 Hz), 1.36 (s, 9H), 1.44-1.68 (m, 5H), 1.84-2.04 (m, 3H), 3.05-3.20 (m, 2H), 3.42-3.53 (m, 1H), 4.19-4.26 (m, 1H), 6.21 (s, 2H), 6.64 (dd, 1H, J=1.8, 8.4 Hz), 6.92 (s, 1H), 7.09 (dd, 1H, J=3.6, 5.1 Hz), 7.26 (s, 1H), 7.29 (s, 1H), 7.58 (d, 1H, J=5.1 Hz), 7.70 (d, 1H, J=3.9 Hz), 10.67 (s, 1H).
