A 7.5 g sample of ethyl 3-(R)-(1-BOC-2-(S)-pyrrolidinyl)-4-nitrobutanoate (prepared according to the procedure of Hayakawa et al., U.S. Pat. No. 5,098,912, issued Mar. 24, 1992) was dissolved in 35 mL of ether and treated with 0.76 g of LAH. After careful quenching of the excess reagents, the title compound was extracted and purified by chromatography (4.5 g).
