Procedure

4-Chloro-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (110 mg, 0.27 mmol) was treated with 2-methoxybenzenethiol (49 μl, 0.40 mmol), copper(I) iodide (77 mg, 0.40 mmol) and potassium carbonate (74 mg, 0.54 mmol) in 2.2 mL dimethylformamide according to the method described in Preparation 86 but heating the reaction mixture at 50° C. overnight. The residue was purified using SP1® Purification System (0% to 15%, hexane-ethyl acetate) to give 69 mg (60% yield) of the title compound.
