To a 1 L 3-neck flask equipped with overhead stirrer was added crude 5-(1-butoxy-vinyl)-4-methyl-3H-isobenzofuran-1-one (55.8 g) and THF (315 mL). The solution was cooled to <5° C. after which water (79 mL) was added and the solution was maintained at <5° C. NBS (41.6 g) was then added portionwise while maintaining Tmax=19° C. The solution was then warmed to RT for 30 minutes. HBr (48%, 0.241 mL) was added and the reaction was aged at RT for approximately 1 h after which 236 mL water was then added to the batch. A water bath is used to maintain temp at 20° C. Another 315 mL of water was added (solvent composition 1:2 THF:water) and the slurry was cooled to 15° C. The resulting solids were filtered and washed with cold 1:2 THF:water (15° C.): 150 mL displacement wash followed by 100 mL slurry wash. The solids were dried under vacuum at RT to provide 5-(2-bromo-acetyl)-4-methyl-3H-isobenzofuran-1-one.

Procedure:
A mixture of 4-{1-[4-(4-chloro-phenoxy)-phenyl]-2-ethoxymethyl-1H-imidazol-4-yl}-phenol (0.21 g, 0.5 mmol, 1.0 eq.) and Cs2CO3 (0.49 g, 1.5 mmol, 3.0 eq.) in DMF (2 mL) was stirred and preheated to 80° C. The reaction mixture was then treated with a solution of (2S)-(+)-glycidyl tosylate (0.17 g, 0.75 mmol, 1.5 eq.) in 1 mL of DMF dropwise, and further stirred at 80° C. for ˜30 min following completion of the addition. Analysis of the reaction by TLC and LC/MS showed that the starting phenol had been consumed and the desired alkylated-phenol was the major product. The reaction was then cooled and diluted with EtOAc and washed with brine. The organic phase was dried with Na2SO4 and evaporated in vacuo. The crude alkylated-phenol was then purified by flash column chromatography over silica gel (EtOAc/hexanes ˜1:3).

Procedure:
t-Butyl 5-bromo-1H-indole-1-carboxylate (200 mg, 0.68 mmol) was placed in a 10 mL sealed tube. Cs2CO3 (440 g, 1.35 mol) was then added, followed by CuI (13 mg, 0.07 mmol), L-proline (16 mg, 0.14 mmol), DMSO (3 mL), and pyrrolidine (480 g, 6.75 mol). After sparging with nitrogen, the resulting solution was stirred at 95° C. for 18 hours. The mixture was extracted with ethyl acetate (3×40 mL), and the organic layers were combined and washed with brine. The residue was purified by column chromatography using 1:5 and 1:2 ethyl acetate/petroleum ether solvent systems. The collected fractions were combined and concentrated to give 100 mg (80%) of 5-(pyrrolidin-1-yl)-1H-indole as brown oil.
