Procedure

To stirred solution of 4-chloro-5-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (Preparation 226, 6.6 g, 22.7 mmol) in THF (130 mL) was added n-BuLi (18.2 mL of a 2.5M solution in hexane, 45 mmol) at −75° C. under N2, and the mixture was stirred for 50 min. A solution of 5-((diphenylmethylene)amino)nicotinaldehyde (Preparation 106, 6.5 g, 22.7 mmol) in dry THF (50 mL) was added and the mixture was stirred at −70° C. for 80 min. The mixture was quenched with sat. aq. NH4Cl solution and extracted with EtOAc (300 mL). The organic layer was dried (Na2SO4) and concentrated in vacuo to give the title compound as a brown solid in 48% yield, 5.2 g.
