Procedure
To a solution of methyl 4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene-2-carboxamido)benzoate 3 (0.200 g, 0.5 mmol) in MeOH (2 mL) was added an hydroxylamine solution (1.76 M, 2 mL) in MeOH and the reaction mixture was stirred 1 h at RT under magnetic stirring. The reaction mixture was adjusted to pH=5, concentrated and the residue was partitioned between EtOAc and H2O. The organic layer was dried with Na2SO4 and the product was crystallized by dissolving the mixture at 80° C. in CH3CN to give N-(4-(hydroxycarbamoyl)phenyl)-5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene-2-carboxamide EHT 3741 (0.070 g, 35% yield) as a pale red solid.
