YieldReaction ConditionsOperation in experiment
40% Intermediate 53:Ethyl 5-bromo-3-(tetrahydro-2H-thiopyran-3-yl)-1H-indole-7-carboxylate.Dihydro-2H-thiopyran-3(4/-/)-one (0.217g, 1.86mmol) was dissolved in dichloromethane (23ml_) in an oven dried flask containing 3 A molecular sieves and stirred under argon at 00C. TMS-OTf (0.414g, 1.86mmol, 0.33 ml.) was added slowly to the mixture over 10 min.Ethyl 5-bromo-1 /-/-indole-7-carboxylate (0.5g, 1.86mmol) was dissolved in DCM (7ml_) and added to the reaction via syringe pump over 2 hours, after which it was stirred for 3 hours between 0 and 10 0C. The reaction was cooled to 0 0C and triethylsilane (0.325g, 0.44ml_, 2.8mmol) was added all at once and the reaction was stirred at room temperature for 18 hours. The reaction was then quenched with a saturated sodium bicarbonate solution and extracted with DCM. The combined organics were washed with water. The combined aqueous layers were back-extracted with DCM. The combined organics were washed with brine, dried with MgSO4, and concentrated. The crude compound was purified on a Combiflash silica column with 5-25% EA/Hexane to give 0.279g (40%) of the title compound.LC/MS: m/z 369 (M+H), Rt 2.74 min.
