To a stirred solution of (5-Bromo-pyridin-3-yl)-{7-[1-(tetrahydro-pyran-2-yloxymethyl)-cyclopropyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}-methanone (Preparation 250, 200 mg, 0.45 mmol) in 1-Methyl-pyrrolidin-2-one (1.5 mL) was added ammonium hydroxide (15 mL). Then copper (I) oxide (3 mg, 0.02 mmol) was added and the reaction mixture was heated in a sealed tube at 130° C. for 16 hours. The reaction mixture was cooled to room temperature, extracted with 10% methanol in dichloromethane (5×25 mL). The combined organic layer was dried over sodium sulphate and evaporated in vacuo. The crude material was purified by column chromatography on silica gel (gradient of dichloromethane:methanol 100:0 to 96:4) to afford the title compound as a white sticky solid in 45% yield, 80 mg.
