Versuchsvorschrift

To 1-[4-({(E)-[(tert-butoxycarbonyl)amino][(tert-butoxycarbonyl)imino]methyl}amino)phenyl]-N-cyclopropyl-D-prolinamide (Method 62; 2.0 g) was added DCM (60 ml) and TFA (20 ml). The reaction stirred for 4 hours before removal of the solvent in vacuo. To the gum was added DCM (75 ml) and macroporous polystyrene carbonate resin (0.49 g of capacity 3.0 m.equ per g) solid supported reagent (20 g), the reaction was slowly stirred overnight. The reaction was filtered and the solvent removed in vacuo to yield very little product. A white solid was present in the filter cup, this was dissolved in MeOH, the resin was also added to the MeOH, the system was stirred for 10 minutes before being filtered, the solvent was removed in vacuo to yield the title compound as a white solid (0.90 g, 75%). NMR (299.954 MHz, CDCl3) δ 7.26 (s, 3H), 6.85 (d, 2H), 6.49 (d, 2H), 3.93 (d, 1H), 3.62-3.60 (m, 1H), 3.17 (q, 1H), 2.70-2.62 (m, 1H), 2.32-2.14 (m, 2H), 2.00-1.92 (m, 2H), 0.76-0.63 (m, 2H), 0.42 (q, 2H); m/z 287.
