Versuchsvorschrift

Trifluoroacetic acid/Dichloromethane (20 ml, 1:1) was added to tert-butyl (2S)-2-[(4-{[(3,4-dichlorophenyl)amino]-carbonyl}piperazin-1-yl)methyl]morpholine-4-carboxylate (2.10 g) under argon and stirred for 1 h. The solvent was then removed on a rotavapor and azeotroped (2×20 ml) with toluene and dried for 24 h under high vacuum to afford the title compound (2.67 g) as a brown oil which was used without further purification.
