Reaction Steps

A solution of N-[4-chloro-5-(3-hydroxy-prop-1-ynyl)-7-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidin-2-yl]-2,2-dimethyl-propionamide (9.0 g, 19.7 mmol) and Et3N (2 mL) in DCM (50 mL) was treated with MsCl (15.3 mL, 19.7 mmol) at 0° C. for 20 min and evaporated to give a yellow solid, containing mostly the desired mesylate (10.7 g). An aliquot of this solid (106.8 mg, 0.2 mmol) was treated with diisopropylamine (20.3 mg, 28.1 μL) in DCM (2 mL) at 0° C. for 10 h, and then at 25° C. for 3 days. Evaporation and preparative plate chromatography gave the title compound.
