実験手順

(R)-1-(4-Amino-phenyl)-pyrrolidine-2-carboxylic acid cyclopropylamide (Method 61; 1.2 g, 4.9 mmol) in DCM (60 ml) was added di-tert-butyl[(Z)-1H-pyrazol-1-ylmethylylidene]biscarbamate (1.9 g, 6.1 mmol) in one portion. The reaction was stirred overnight before removal of the solvent in vacuo. The residue was purified via column chromatography eluting with 20% ethylactetate/isohexane, 50% EtOAc/isohexane and finally 100% EtOAc. The title compound was obtained as a white foam (2.0 g, 81%). NMR (299.954 MHz, CDCl3) 11.63 (s, 1H), 10.09 (s, 1H), 7.60 (s, 1H), 7.40 (d, 2H), 6.45 (m, 3H), 3.92 (t, 1H), 3.59 (t, 1H), 3.19 (q, 1H), 2.69 (m, 1H), 2.29-2.22 (m, 2H), 2.03-1.84 (m, 2H), 1.53 (s, 9H), 1.49 (s, 9H), 0.80-0.68 (m, 2H), 0.44-0.32 (m, 2H); m/z 488.
