Reaction Steps

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), 4-(3-chloropropyl)morpholine (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. Product was extracted with ethyl acetate (100 mL), organic phase washed with water (3×10 mL) and brine (2×10 mL), then dried over Na2SO4, filtered and concentrated to afford N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-2-(6-methyl-1-(3-morpholinopropyl)-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (95 mg, crude) as a yellow oil. LCMS: (M+H)+=848.
