Procedure

To a solution of 2-(2-phenyltetrahydro-2H-pyran-2-yl)acetaldehyde (100 mg, 0.490 mmol) and sulfamic acid (57.0 mg, 0.587 mmol) in THF (1.5 mL) was added a solution of sodium chlorite (53.1 mg, 0.587 mmol) in water (1.5 mL) dropwise, and the mixture was stirred at room temperature for 3 hrs. Then the product was extracted with EtOAc (3×) and the combined extracts were washed with brine, dried over Na2SO4, and evaporated to give 2-(2-phenyltetrahydro-2H-pyran-2-yl)acetic acid as oil. LC/MS: m/e 221.14 (M+H)+.
