Procedure
To a solution of 6-Methyl-2-(3,4,5-trimethoxy-phenyl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (95 mg) in 1.5 mL of DMF was added PyBOP (128 mg) followed by tert-Butyl amine (70 mg). After stirring for 2 h, the mixture was partitioned between water and diethylether. The organic phase was washed with brine, dried over Na2SO4, filtered, and concentrated. Flash chromatography (4:1 Hexanes:ethylacetate) afforded 70 mg of 6-Methyl-2-(3,4,5-trimethoxy-phenyl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid tert-butylamide.
