Procedure

A mixture of N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-2-(6-methyl-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (100 mg, 0.139 mmol), 2-chloro-1-morpholinoethanone (27 mg, 0.166 mmol) and K2CO3 (58 mg, 0.417 mmol) in dry DMF (20 mL) was heated to 90° C. for 3 hours. After cooling to room temperature, ethyl acetate (100 mL) was added, and the solution was washed with water (3×10 mL) and brine (2×10 mL). The combined organic layers were dried over Na2SO4, concentrated to give the residue which was used into the next step without further purification. LCMS: (M+H)+=848.
