Procedure:
Under ice-cooling, piperidine (0.094 mL) was added to an acetone (1.5 mL) suspension of tert-butyl 2-(5-(bromomethyl)-2-(methoxymethoxy)benzamido)-4-phenylbenzoate (0.10 g), followed by stirring at room temperature for 1 hour. The solvent was evaporated under reduced pressure, and a saturated aqueous solution of sodium bicarbonate and ethyl acetate were added to the residue. The organic layer was separated, washed with a saturated aqueous solution of sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure.

Procedure:
To a solution of ethyl 2-(5-cyclopentyl-2-methyl-3-(2-(pyrrolidin-1-ylsulfonyl)benzyl)-1H-pyrrol-1-yl)acetate (2.54 g, 5.54 mmol) in acetonitrile (28 mL) was added chlorosulfonyl isocyanate (0.818 ml, 9.42 mmol). The reaction was stirred at room temperature for 30 minutes, after which the starting pyrrole had still not been consumed. The reaction was then heated to 55° C. for 30 minutes after which the starting pyrrole was consumed (by LCMS analysis). To the reaction mixture at 55° C. was added N,N-dimethylformamide (0.729 ml, 9.42 mmol). The reaction was stirred at 55° C. for 30 minutes after which analysis of the reaction (by LCMS) indicated that the reaction to afford the desired product was complete. The reaction was quenched by the addition of water, and extracted with dichloromethane (3×50 mL), dried (sodium sulfate), filtered and concentrated to a deep maroon residue. Purification was achieved by silica gel chromatography (Luknova 240 g, 20 mL/min) using 1 to 7% of a 7:1 acetonitrile/methanol solution in dichloromethane over 70 minutes. The product ethyl 2-(3-cyano-2-cyclopentyl-5-methyl-4-(2-(pyrrolidin-1-ylsulfonyl)benzyl)-1H-pyrrol-1-yl)acetate (747 mg, 1.55 mmol, 28% yield) was isolated as a white foam. 1H NMR (400 MHz, CDCl3) δ (ppm): 8.01 (d, 1H), 7.40 (dd, 1H), 7.30 (ddd, 1H), 6.99 (d, 1H), 4.59 (s, 2H), 4.30 (s, 2H), 4.27 (q, 2H), 3.32-3.36 (m, 4H), 2.96 (m, 1H), 1.84-2.09 (m, 13H, composite of multiple shifts), 1.63-1.71 (m, 2H).

Procedure:
A solution of 2.07 g of ethyl (2R,3S)-3-cyclopropyl-3-tert-butoxycarbonylamino-2-hydroxypropionate and 213 mg of pyridinium p-toluenesulfonate in 125 ml of toluene is refluxed under heating. To the mixture is added dropwise a solution of 2.76 g of p-anisaldehydedimethylacetal in 25 ml of toluene for 20 minutes. The reaction mixture is evaporated to remove the generated methanol. The mixture is stirred under heating for 1.5 hours and cooled. After the reaction mixture is condensed under reduced pressure, ethyl acetate and water are added to the residue. The ethyl acetate layer is obtained by separation. The aqueous layer is extracted with ethyl acetate. The extract is washed with water and brine, dried and condensed under reduced pressure. The residue is purified by silica gel column chromatography (solvent; toluene:ethyl acetate=40:l) to give 1.572 g of ethyl (4S,5R)-3-tert-butoxycarbonyl-2-(4-methoxyphenyl)-4-cyclopropyl-5-oxazolidinecarboxylate (diastereomeric mixture).
