Versuchsvorschrift

To a solution of (2S,4S)-4-(9H-fluoren-9-ylmethoxycarbonylamino)-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester (Aldrich) (7.5 g, 16.593 mmol) in DMF (100 mL) were added HATU (6.93 g, 18.252 mmol) and DIPEA (14.36 mL, 82.965 mmol) and the mixture was cooled to 0° C. (R)-(1,2,3,4-tetrahydro-naphthalen-1-yl)amine (2.44 g, 16.593 mmol) was added dropwise and the cooling bath removed. After 4 h the mixture was diluted with ethyl acetate, washed with water, dried over sodium sulfate and concentrated to afford the title compound as an off white solid (9.6 g) which was used without purification. LC-MS: 582 (M+H).
