Versuchsvorschrift

A mixture of 2-({2-methyl-3-[4-phenyl-5-(1H-1,2,4-triazol-3-yl)-1,3-thiazol-2-yl]pyrazolo[1,5-a]pyridin-5-yl}oxy)ethanamine di-hydrochloride (100 mg, 0.20 mmol) obtained in Example 73-B(i), TEA (1.5 mL), 1-methyl-1H-imidazole-4-carboxylic acid (120 mg, 0.95 mmol), HOBT (220 mg, 1.6 mmol), EDCI (350 mg, 1.8 mmol) and DMF (10 mL) was stirred at rt for 14 h. To the reaction mixture were added water (200 mL) and EtOAc (200 mL) and the mixture was stirred for 30 min. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. Insoluble materials were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was washed with EtOAc and diisopropyl ether, and dried to give the title compound (31 mg, 29%) as a yellow solid.
