Prepare a solution of N-(2-hydroxypropyl)benzamide (8.22 g, 45.9 mmol) in methylene chloride (100 mL). Add N-methylmorpholine N-oxide (7.0 g, 60.0 mmol) followed by powdered 4 Å molecular sieves. Cool the mixture to 0° C. and add tetra-n-propylammonium perruthenate in one portion. Stir the mixture for 30 minutes and then warm to room temperature for 1 hour and filter through Celite®. Concentrate the filtrate and flash-chromatograph on silica gel eluting with 100% ethyl acetate to afford 6.1 g of N-(2-oxopropyl)benzamide as a white solid. MS: m/e=178 (MH+)
