Procedure

The acid chloride obtained starting from 6.5 g (28.5 mmol) of the acid obtained in Step E and 5 ml of oxalyl chloride are added dropwise to a suspension of N,O-dimethylhydroxylamine chloride (5.6 g) in a mixture of CH2Cl2/H2O in the presence of 3 g of Na2CO3. The protected acid is obtained in the form of a pale yellow solid.
