Procedure

A solution of 1,1-dimethylethyl (2S,5R)-2-(aminocarbonyl)-5-(4-hydroxyphenyl)-2-methyl-1-pyrrolidinecarboxylate (D10, 60 mg, 0.187 mmol), 2-fluorobenzonitrile (45 mg, 0.374 mmol) and potassium carbonate (39 mg, 0.280 mmol) in DMF (2 ml) was heated under microwave irradiation for 30 min to 120° C. Water and ethyl acetate were added to the mixture, and the organic layer was washed with ice cold water. The solution was dried (Na2SO4) and evaporated. The crude material was purified by chromatography on silica gel using cyclohexane/ethyl acetate (7:3 to 6:4) to afford the title compound (78 mg); Rt (HPLC): 5.44 min; Rf (cyclohexane:ethyl acetate=1:1): 0.21; MS: (ES/+) m/z: 444 [M+Na+]; C24H27N3O4 requires 421.
