実験手順

3-tert-Butyl-5-[3-(tetrahydropyran-2-yloxy)propoxy]benzoic acid (O4.059; 4.90 g) and N,O-dimethylhydroxylaminehydrochloride (1.42 g) were dissolved in DMF (80 ml) and admixed with Hünig's base (4.81 ml) and TOTU (4.78 g). After stirring for 2 h, the mixture was left to stand overnight. Then the DMF was drawn off, the mixture was partitioned between EA and saturated sodium hydrogencarbonate solution, and the EA phase was removed, dried over magnesium sulfate, filtered and concentrated. 5.49 g of the title compound were obtained.
