Versuchsvorschrift

Hydroxybenzotriazole (121 mg, 1 mmol), diisopropylethylamine (23 2 mg, 2 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (172 mg, 1 mmol) were added to a cooled (0° C.) solution of (S)-3-amino-1-cyclopropyl-5-methyl-1,3,4,5-tetrahydro-benzo[b][1,4]diazepin-2-one (220 mg, 1 mmol) and L-(+)-lactic acid (81 mg, 1 mmol) in THF (2 ml) and stirred overnight at r.t. The solvent was evaporated, the residue was taken up in dichloromethane and washed with water. The organic phase was dried over Na2SO4 and evaporated. Upon chromatographic purification (silica gel, dichloromethane/methanol=1:0−9:1) the title compound (347 mg, quant.) was obtained as a white solid.
