Procedimiento

200 μl of a 0.05 molar solution of 4-{2-[(5-chloro-thiophene-2-carbonyl)-amino]-2-methyl-propionylamino}-2-methyl-benzoic acid, which additionally contains 0.05 mol/l DIPEA, in DMF are combined with 100 μl of a 0.1-molar solution of TBTU in DMF on a microtitre plate and mixed for 10 mins on a shaker. Then 200 μl of a 0,05-molar solution of (3-hydroxy-prop-1-yl)-piperidine, which additionally contains 0.05 mol/l DIPEA, are pipetted in and again mixed in by shaking. After 16 h at ambient temperature the mixture is filtered through basic aluminium oxide and washed with DMF/methanol=9:1. Then it is evaporated down i. vac.
