Versuchsvorschrift
(2-Amino-4-trifluoromethyl-phenyl)-carbamic acid tert-butyl ester (570 mg) was dissolved in CH2Cl2 (15 ml) and DMF (5 ml) prior to the addition of DIEA (2.3 ml) and malonic acid monobenzyl ester (400 mg). After cooling to 0° C., HATU (940 mg) was added. The resulting mixture was warmed to rt and stirred overnight before being concentrated. Flash chromatography of the resulting residue gave N-(2-tert-butoxycarbonylamino-5-trifluoromethyl-phenyl)-malonamic acid benzyl ester (570 mg), MS found: (M−H)−=451.2.
