Procedure

Analogously to Example 194A, 500 mg of 8-[(2,6-difluorobenzyl)oxy]-N-[(2R)-1-hydroxypropan-2-yl]-2-methylimidazo[1,2-a]pyridine-3-carboxamide (Example 177A, 1.33 mmol) were oxidized with 847 mg (2.0 mmol) of Dess-Martin periodinane with addition of 0.11 ml of pyridine (105 mg, 1.33 mmol) and worked up. This gave 440 mg (53% of theory; purity 60%) of the title compound which was reacted further without purification.
