Reaction Conditions

Reaction Steps

2,4,6-Trichloro-1,3,5-triazine (XVIII) (30 g, 163 mmol) was dissolved in acetone (300 mL), and N,O-dimethylhydroxylamine hydrochloride (15.8 g, 163 mmol) and DIPEA (42 g, 326 mmol) were added and the mixture then stirred at 0° C. for 1 h. The solution was concentrated and the residue was treated with EtOAc (750 mL), washed with water (100 mL), and the organic layer was dried with Na2SO4. The volatiles were removed in vacuo and the residue was purified by flash column chromatography (pet ether/ethyl acetate=50/1 to 10/1) to yield the desired product, N-(4,6-dichloro[1,3,5]triazin-2-yl)-N,O-dimethyl-hydroxylamine (XXX), as a white solid (25 g, 73% yield). LCMS (ESI) m/z=210 (M+H)+.
