Versuchsvorschrift

A mixture of ethyl 4-(4-(4-(6-(tert-butoxycarbonylamino)hexyloxy)benzylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoate (1.0 g) and K2CO3 (1.25 g) in acetone (12 mL)/water (12 mL) was heated at 110° C. for 24 hours. After cooling to room temperature, the mixture was acidified with 1N HCl to pH=3. The white precipitate was collected, washed with water (20 mL) and dried under vacuum to give 4-(4-(4-(6-(tert-butoxycarbonylamino)hexyloxy)benzylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoic acid (0.72 g).
