In three 2-5 mL microwave vials was each placed 3-(2,6-dichloropyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (9, 100 mg, 0.384 mmol) in THF (2 ml). A 1N solution of sodium hydroxide (2 ml, 2.000 mmol) was added to each vial. The reaction was heated under microwave irradiation at 150° C. for 30 min. The contents of the three microwave vials were combined, 6 mL 2N HCl was added to acidify (pH˜3). Silica gel was added and the mixture was concentrate purify by silica gel chromatography, using a gradient (0-15%) of MeOH in dichloromethane to give 205 mg (0.85 mmol, 74%) of the title compound as a white solid.
