Versuchsvorschrift

A mixture of 5-(3-aminopyrrolidin-1-yl)-N-(3,4-dimethoxyphenyl)thiazolo[5,4-d]pyrimidin-7-amine hydrochloride (164 mg, 0.4 mmol), 3-hydroxy-4-(methoxycarbonyl)benzoic acid (78 mg, 0.4 mmol), EDCI (153 mg, 0.8 mmol) and N-methylimidazole (100 mg, 1.2 mmol) in 5 mL of DCM was stirred at room temperature for 16 hours. The mixture was washed with water (4 mL), The organic layer was dried over Na2SO4. After filtration and concentration, the residue was purified by column chromatography (silica gel, 100% DCM to DCM:MeOH=50:1) to give methyl 4-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-ylcarbamoyl)-2-hydroxybenzoate (100 mg, yield 45%). LC-MS: 551 [M+H]+, tR=1.61 min.
