Versuchsvorschrift

To a solution of 6-bromo-1-cyclopentyl-1H-indazole-4-carboxylic acid (2.3 g, 7.5 mmol) in DMSO (30 mL), PyBOP (5.82 g, 11.20 mmol) was added and reaction stirred at room temperature for 15 min. 3-(Aminomethyl)-4-(((tert-butyldimethylsilyl)oxy)methyl)-6-methylpyridin-2(1H)-one (2.52 g, 8.96 mmol) was then added and reaction mixture stirred overnight. On completion, water was added and the resulting precipitate filtered and washed with water. This solid was then stirred with acetonitrile for 10 min and filtered again to obtain 6-bromo-1-cyclopentyl-N-((4-(hydroxymethyl)-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1H-indazole-4-carboxamide (1.4 g, 40.9%).
