Reaction Conditions

Reaction Steps

To a solution of 5-methoxyindan-1-one (75.8 g; 0.467 mol) in MeOH (1.4 L) at 45° C. is added butyl nitrite (81 mL; 0.693 mol) dropwise over 45 min. Concentrated HCl (45 mL) is then added to the hot solution over 20 min and the reaction was allowed to stir at 45° C. for an additional 1.5-2 h. The reaction suspension is cooled, the precipitate filtered, washed several times with cold MeOH, and dried under vacuo to afford 55.8 g (62%) of 5-methoxyindan-1,2-dione-2-oxime as a beige solid.
