実験手順
To a homogeneous, colorless solution of 2-(hydroxymethyl)-5-methylbenzoic acid (0.6325 g, 3.81 mmol) in THF (35 mL) under nitrogen was added MnO2 (4.96 g, 57.1 mmol), and the reaction was stirred overnight. Additional MnO2 (˜3 g) was added, and the reaction was stirred overnight. The mixture was filtered through a pad of CELITE® and rinsed with THF. The filtrate was concentrated in vacuo to give the desired product (0.3302 g, 2.011 mmol, 52.8% yield) as an off-white solid.
