Intermediate 72:(racem/cJ-Ethyl 5-bromo-3-(2,2-dimethyltetrahydro-2H-thiopyran-4-yl)-1H-indole-7- carboxylate.2,2-Dimethyltetrahydro-4H-thiopyran-4-one (0.675 g, 4.68 mmol) was placed in a dried flask fitted up with an addition funnel, a septum and an argon inlet, and dissolved in dry DCM (15 mL), cooled to 0 0C, stirred, and then trimethylsilyl trifluoromethanesulfonate (1.692 mL, 9.36 mmol) was added dropwise through the addition funnel over 10 minutes. DCM (5 mL) was used to wash the addition funnel walls. To this mixture was added dropwise ethyl 5-bromo-1 H-indole-7- carboxylate (1.341 g, 5 mmol) in DCM (15 mL) over 2 hours. Then triethylsilane (2.98 mL, 18.73 mmol) was added in one portion. The mixture was stirred 2 h at 0 0C, and left stirring at 23 0C overnight. The reaction was quenched with a saturated aqueous solution of sodium bicarbonate, and the resulting biphasic mixture extracted with DCM to give 2.1 15 g of the title compound. LC/MS: m/z 398.0 (M+H), Rt 1.49 min., 1065181-58-9

The synthetic route of 1065181-58-9 has been constantly updated, and we look forward to future research findings.
