Intermediate 20A. Preparation of 4-iodobicyclo[2.2.2]octane-1-carbonitrile To a 250 mL round bottomed flask were added Intermediate 4B (0.56 g, 2.0 mmol), THF (20 mL) and TEA (0.42 mL, 3.0 mmol). The mixture was cooled to -30° C., then ethyl chloroformate (0.23 mL, 2.4 mmol) was added dropwise. The mixture was stirred for 1 h at -30° C. The reaction was filtered, both flask and filter cake were washed with an additional amount of ice cold THF (15 mL), and the reaction was cooled to -20° C. The mixture generated above was cooled to -20° C. and ammonia gas was dispersed through the mixture for 10 min. After stirring at this temperature for 40 min, the solvent was concentrated and the residue was taken onto the next step without purification or characterization. The residue from above was dissolved in THF (12 mL), pyridine (0.53 mL, 6.6 mmol) was added and the mixture was cooled to 0° C. To this mixture was added trifluoroacetic anhydride (0.57 mL, 4.0 mmol) and the reaction was stirred at this temperature for 2 h. To this mixture was added MeOH (5 mL) and 1 M K2HPO4 (aq.) (5 mL) and stirred for 30 min. The mixture was diluted with water (100 mL) and extracted with EtOAc (2×50 mL). The organic phase was combined, washed with 1 M HCl (aq.), brine, dried over Na2SO4, filtered and concentrated. The crude product was purified by flash column chromatography (40 g silica gel cartridge; A=Hex, B=EtOAc; 20 min grad.; 0% B to 50% B; flow rate=40 mL/min). The pure fractions were combined, concentrated and dried in vacuo to afford the title compound (0.37 g, 1.4 mmol, 71% yield) as a white solid. 1H NMR (500 MHz, CHLOROFORM-d) δ 2.56-2.46 (m, 6H), 2.14-2.04 (m, 6H).
