A mixture of 4-(2-fluoropyridin-3-yl)-7H-pyrrolo[2,3-d]pyrimidine (78 mg, 363 μmol) and 4-(8-amino-7-methylquinazolin-4-ylamino)benzonitrile (100 mg, 363 μmol) in THF (4 mL) was sonicated until all solids became a fine powder. Lithium bis(trimethylsilyl)amide (1.0 M solution in tetrahydrofuran; 1.64 mL, 1.64 mmol) was then added dropwise with stirring (all solids dissolved and then some solid appeared again). The mixture was stirred at rt for 10 min and then heated in a microwave at 120° C. for 30 min. The mixture was poured into MeOH (10 mL) and AcOH (0.5 mL) and stirred for 10 min, then 2 M NH3 in MeOH (20 mL) was added. Solvent was removed under vacuum and the residue was purified by flash chromatography eluting with MeOH(NH3)/DCM to give 4-(8-(3-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)pyridin-2-ylamino)-7-methylquinazolin-4-ylamino)benzonitrile. MS (ESI, pos. ion) m/z: 470.2 [M+H]+
