Procedure

A mixture of 1.0 eq of 5,6,7,8-tetrahydroquinolinone-5 (93) (Tyger Scientific, Ti 1850), 3.0 eq of hydroxylamine hydrochloride (Aldrich, 37,992-1), and 3.0 eq of sodium acetate in 50 mL of MeOH and 15 mL of H2O was refluxed for 4 hrs. The mixture was allowed to cool to rt. After rotary evaporation of the MeOH, 100 mL of H2O was added. The solid formed was collected by vacuum filtration. The solid collected was triturated with hexanes and dried under vacuum to give 94.
