| Experimental Procedure 3-(N-tosyl-L-alaninyloxy)-5-phenylpyrrole (4) 3-(N-tosyl-L-alaninyloxy)-5-phenylpyrrole (4) A solution of anhydrous tetrahydrofuran (THF, 450 mL), pyridine (43.8 mL; 0.542 mol; 1.2 eq) and trifluoroacetic acid (85.0 mL; 1.10 mol; 2.4 eq), maintained at 0° C. under an inert gas atmosphere, was treated in one portion with 3-hydroxy-5-phenylpyrrole (3) (71.5 g; 0.45 mol; 1.0 eq) followed immediately by the dropwise addition, over 5-10 minutes of a solution of freshly prepared N-tosyl-L-alaninyl chloride (141.0 g; 0.54 mol; 1.2 eq) in anhydrous THF (450 mL). The resulting mixture was stirred for 15 minutes at 0° C. The reaction was then quenched by addition of a solution of 1.0M aqueous citric acid (315 mL) and EtOAc (1.35 L). After brief mixing the phases were separated and the organic layer washed with a solution of aqueous NaCl (360 mL; 0.18 g NaCl per mL of water). The organic layer was next extracted twice with a solution of 5% aqueous NaHCO3 (1.35 L each), and then washed with another portion of aqueous NaCl (360 mL; 0.18 g NaCl per mL of water). The reddish brown organic layer was stirred at ambient temperature for 15 minutes with MgSO4 (101 g) and Darco-G60 (143 g), then filtered through Celite and evaporated to dryness in vacuo from a 37° bath to give (4) as a pinkish-white solid. | 99% |
