Reaction Conditions

Reaction Steps

A flask was charged with (3-methyl-4-nitro-phenyl)-methanol (66.9 g, 0.400 mol), manganese(IV) oxide (85%, 5 μm powder, 409.1 g, 4.00 mol), and CH2Cl2 (1337 mL). The mixture was stirred at 40° C. for at least 2 h or until HPLC analysis showed that the reaction had proceeded to greater the 97% completion. The cooled batch was diluted with CH2Cl2 (1 L) and filtered through a Celite® pad (34 g), and the filter cake was rinsed with more CH2Cl2 (1 L). The filtrate and washes were concentrated under in vacuo to dryness to give the title compound as a yellow solid (58 g, 87% yield).
