Intermediate 87:Ethyl 5-bromo-3-(2-phenyltetrahydro-2H-thiopyran-4-yl)-1H-indole-7-carboxylate.To a solution of 2-phenylthian-4-one (SJTU) (0.900 g, 4.68 mmol) in dichloromethane (DCM) (15 ml_), cooled on an ice bath to 0 0C, under argon, was added dropwise trimethylsilyl trifluoromethanesulfonate (1.807 ml_, 10 mmol) over 10 minutes, an additional portion of dry DCM (5 ml.) was used to wash the addition funnel walls. To this mixture ethyl 5-bromo-1 H-indole-7- carboxylate (1.340 g, 5.00 mmol) was added dropwise, in solution with of dry DCM, over 2 hours. Finally, triethylsilane (3.19 ml_, 20 mmol) was added in one portion and the mixture was stirred 2 h at ca 0 0C, and left stirring at 23 0C 16 h. The reaction was quenched with a saturated aqueous solution of sodium bicarbonate, and the resulting biphasic mixture partitioned with DCM to afford 2.21 g of brow gummy oil. LCMS of product may indicate an overlapping mixture of ca 5:2 major to minor isomers (cis/trans). LC/MS: m/z 448.1 (M+H), Rt 3.23 min.

Intermediate 31 :Ethyl 5-bromo-3-(8-thiabicyclo[3.2.1]oct-3-yl)-1H-indole-7-carboxylate.To a solution of 8-thiabicyclo[3.2.1]octan-3-one (1.33 g, 9.32 mmol, 1 eq) in dry dichloromethane (50 mL) was added a spatula tip full of activated 4A molecular sieves (beads). The ketone solution was cooled to 0 0C, and trimethylsilyl triflate (1.7 mL, 9.41 mmol, 1 eq) was added dropwise followed by a solution of ethyl 5-bromo-1 H-indole-7- carboxylate (2.5 g, 9.32 mmol, 1 eq) in dichloromethane (25 mL). The mixture was stirred at 23 0C overnight, then was cooled to 23 0C and triethylsilane (2.3 mL, 14.4 mmol, 1.5 eq) was added in a single portion. The reaction was stirred at 23 0C for 1.5h, then quenched by the addition of saturated aqueous sodium bicarbonate. The mixture was extracted with dichloromethane, and the combined organic extracts were dried over sodium sulfate, filtered, and concentrated. The crude product was purified by lsco Combiflash, 120 gram column, eluting with 0-30% ethyl acetate in hexanes. The ethyl 5-bromo-3-(8- thiabicyclo[3.2.1]oct-3-yl)-1 /-/-indole-7-carboxylate was obtained as a mixture of isomers (2.38 g, 65%).

66% Intermediate 98:Ethyl 5-bromo-3-(tetrahydro-2H-thiopyran-3-ylmethyl)-1H-indole-7-carboxylate.To a 100 ml. three-necked flask equipped with an addition funnel was added tetrahydro- 2H-thiopyran-3-carbaldehyde (2.50 g, 0.019 mol) and dry DCM (30 ml_). Trimethylsilyl trifluoromethanesulfonate was put in the addition funnel. The mixture was cooled down to0 0C with an ice bath and put under nitrogen atmosphere. Trimethylsilyl trifluoromethanesulfonate was added over 15 min, and 10 ml. of dry DCM were used to wash the addition funnel walls. A solution of ethyl 5-bromo-1 H-indole-7-carboxylate in 30 ml. dry DCM was added to the mixture for 2 h at 0 0C, and the mixture was then stirred at room tmperature overnight. An aqueous solution of sodium bicarbonate was added, the layers were separated, and the mixture was extracted with DCM (3 x 100 ml_). The combined organic layers were dried (Na2SO4), filtered, and purified by chromatography, eluting with a mixture of PE:EA (50:1-30:1 ) to afford 4.82 g (66.0%) of the title compound. 1H NMR NMR (CDCI3) delta 1.1 1-1.15 (m,1 H),1.43 (t,3H),1.65-1.71 (m,2H),1.83-1.87 (m,1 H),1.96-2.03 (m,2H), 2.32-2.38 (m,1 H), 2.51-2.59 (m, 2H),2.66-2.68 (m, 2H), 4.40-4.45 (q,2H), 7.07 (d, 1 H),7.77 (d, 1 H), 7.95 (d, 1 H), 9.64 (s, 1 H).
