Reaction Steps

To a suspension of the 6-(6-oxa-3-azabicyclo[3.1.0]hexan-3-yl)-2-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide (0.050 g, 0.13 mmol) in THF (5 mL) and water (1 mL) was added a 60% HClO4 solution (0.1 mL). After stirring overnight, the reaction was heated at 50° C. for 2 days. After the reaction cooled it was quenched with solid NaHCO3 and evaporated in vacuo. The residue was chromatographed over silica gel with 50-100% acetone in hexanes. The product fractions were evaporated and the resulting residue dissolved in 1 mL acetonitrile with warming. Upon cooling a solid formed. The solid was filtered and rinsed once with 1 mL acetonitrile. The remaining solid was suspended in 1 mL warm acetonitrile, filtered and air-dried to give 6-(3,4-dihydroxypyrrolidin-1-yl)-2-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide as a fine crystalline powder (0.009 g, 0.02 mmol, 17%). 1H NMR (400 MHz, DMSO-d6): 8.55 (2H, d, J=8.8 Hz), 8.34 (1H, d, J=2.4 Hz), 7.88 (1H, d, J=2.4 Hz), 7.31-7.24 (2H, m), 7.19-7.13 (2H, m), 7.05 (2H, d, J=9.0 Hz), 6.90 (1H, s), 5.29 (1H, d, J=3.7 Hz), 5.22 (1H, d, J=3.3 Hz), 4.14-4.10 (1H, m), 4.09-4.05 (1H, m), 3.76-3.63 (3H, m), 3.35-3.30 (1H, m). LC/MS: m/z=411.1 [M+H]+.
