Reaction Steps
To a solution of (3SR,4RS)-1-benzyl-4-(3,4-dichloro-phenyl)-pyrrolidine-3-carboxylic acid ethyl ester (1.00 g, 2.64 mmol) in THF (15 mL) at 0° C. were added portion wise LiAlH4 (211 mg, 5.56 mmol). Stirring was continued for 2 hours, and the reaction mixture was quenched by addition of aq. NH4Cl, concentrated under vacuo and the product extracted with EtOAC. The combined organic phases were dried on Na2SO4 and concentrated under vacuo. Flash chromatography (SiO2, EtOAc) to yield 0.70 g (79%) of the title product as a white solid ES-MS m/e: 336.3 (M+H+).
