Procedure

2-[[2-(5-Isopropylthieno[2,3-d]pyrimidin-4-yl)-2-azabicyclo[2.2.1]heptan-5-yl]oxy]ethyl methanesulfonate (0.11 g, 0.27 mmol), 2-oxa-5-azabicyclo[2.2.1]heptane hydrochloride (0.072 g, 0.53 mmol) and potassium carbonate (0.11 g, 0.80 mmol) were combined in methyl ethyl ketone (2 mL)/DMF (1 mL, 12.8) and heated in the microwave for 30 minutes at 180° C. The reaction mixture was diluted with DCM, washed with water, dried over Na2SO4 and concentrated at reduced pressure. The resulting residue was purified by basic prep HPLC (method 2) to afford 5-[2-[[2-(5-isopropylthieno[2,3-d]pyrimidin-4-yl)-2-azabicyclo[2.2.1]heptan-5-yl]oxy]ethyl]-2-oxa-5-azabicyclo[2.2.1]heptane as a colourless gum (20 mg). LCMS RT=4.33 min. M+1=415.
