Versuchsvorschrift

A 4N HCl solution in EtOAc (18 mL) was added slowly to a stirred solution of 4-(4-{(S)-1-[tert-butoxycarbonyl-(2-{2-chloro-4-[3-(5-cyano-pyrazin-2-yl)-ureido]-5-methoxy-phenyl}-ethyl)-amino]ethyl}-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (0.1 g) in EtOAc (100 mL) at 0° C. The mixture was allowed to warm to room temperature and stirred for 8 hours. Diethyl ether (50 mL) was added and stirring continued for 15 minutes. The supernatant was decanted and the isolated solid triturated again with diethyl ether (50 mL). The solid was dried under reduced pressure then dissolved in methanol and precipitated back out of solution using diethyl ether. The isolated solid was further triturated with diethyl ether then dried under reduced pressure. The obtained solid was triturated with ethyl acetate, acetone, ethanol followed by diethyl ether and dried at reduced pressure to give the title compound (0.025 g, 34%) as a white solid.
