Reactions of anilines with ethyl bromoacetate under microwave irradiation have afforded N-arylglycines that are subsequently converted to their N-nitroso derivatives with a combination of silica chloride or periodic acid, wet SiO2 and sodium nitrite in CH2Cl2 with satisfactory yields. In the final step, the use of 1,3-dibromo-5,5-dimethylhydantoin (DBH) as a new and effective reagent for dehydration of N-nitroso-N-arylglycines to sydnones was successfully examined.
