Participants

Reaction Steps

To a 25 mL vial which contained a suspension of NaH (60% in mineral oil, 60 mg, 1.5 mmol) in DMF (10 mL) was the product from step 3 (310 mg, 1 mmol) at 0° C. The mixture was allowed to warm to rt and stir at rt for 30 min then cooled to 0° C. To this reaction mixture was added (R)-2-(toluene-4-sulfonyloxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (355 mg, 1 mmol) at 0° C. The resulting mixture was allowed warm to rt and stir at rt for 30 min and then was heated to 90° C. and stirred at 90° C. for 16 h. After cooling to rt, the mixture was poured onto 200 mL ice-water solution and this solution was allowed to stir at 0° C. for 30 min. The solid which formed was filtered out, dried through air to afford the title product (290 mg, 59%); 1H NMR (400 MHz, CDCl3); δ 1.47 (s, 9H), 1.79-2.08 (m, 4H), 3.26-3.46 (m, 2H), 3.70-3.93 (m, 1H), 3.85 (s, 2H), 4.02-4.19 (m, 2H), 6.82-6.88 (m, 2H), 6.91 (d, J=7.6 Hz, 2H), 7.04 (d, J=8.0 Hz, 2H), 7.58 (d, J=8.0 Hz, 2H):
