Reaction Steps

(2S,5R)5-(3,4-Dimethoxy-phenyl)-pyrrolidine-2-carboxylic acid (4-chloro-3-methoxy-phenyl)-amide was dissolved in anhydrous THF and cooled to 0° C. in an ice bath. A 0.5M solution of alane complex in toluene (42.6 ml, 21.3 mmol, 3.0 equivalents) was added slowly and the reaction was allowed to stir and warn to room temperature overnight. The reaction was quenched upon addition of ethyl acetate:methanol (1:1, 5 ml). The resulting slurry was filtered through Celite and rinsed with ethyl acetate. The filtrate was concentrated in vacuo to afford (2S,5R)(4-chloro-3-methoxy-phenyl)-[5-(3,3-dimethoxy-phenyl)-pyrrolidin-2-ylmethyl]-amine (1.80 g, 4.78 mmol, 67% yield). Analysis H1 NMR (400 MHz, CDCl3): 7.12 (1H, d), 6.98–6.90 (3H, m), 6.23 (1H, s), 6.19 (1H, d) 4.39-4.15 (2H, m), 3.76-3.53 (1H, m), 3.30–2.97 (2H, m), 2.34–1.55 (6H, m). MS (LC-MS): Calculated for C20H25ClN2O3 376.16. Found 377.21 (M+H)+.
