Reaction Steps

A solution of (R)-1-methyl-1,4,5,6-tetrahydro-pyrrolo[3,4-c]pyrazole-4-carboxylic acid [2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenyl]-amide (example 1B), 38 mg), 6-indolecarboxylic acid (22 mg), 0.03 ml (DIPEA) and BOPCl (51 mg) in 2 ml acetonitrile was stirred for 2 hrs at 0° C. A consecutive basic and acidic work up delivered a yellow oil which was purified by chromatography (silica gel, AcOEt). (R)-5-(1H-Indole-6-carbonyl)-1-methyl-1,4,5,6-tetrahydro-pyrrolo[3,4-c]pyrazole-4-carboxylic acid [2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenyl]-amide was obtained as a white solid (13 mg). MS: 497.0 (M+H)+
