A solution of 2-(7-chloro-thieno[3,2-b]pyridin-2-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [(R)-2-(3-cyano-azetidin-1-yl)-1-cyclopropyl-2-oxo-ethyl]-amide (40 mg, 0.064 mmol) in pyrrolidine (5.32 ml, 64.3 mmol) was heated in a microwave reactor at 100° C. for 2 h. The reaction mixture was evaporated to dryness under vacuum. The crude residue was suspended in MeOH (0.5 mL) and the resultant solid collected by filtration, washing with MeOH, to give 36 mg (85%) 2-(7-pyrrolidin-1-yl-thieno[3,2-b]pyridin-2-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [(R)-2-(3-cyano-azetidin-1-yl)-1-cyclopropyl-2-oxo-ethyl]-amide.
