Reaction Steps

A mixture of 6-chloro-N,N′-dipropyl-[1,3,5]triazine-2,4-diamine (XXXIV) (2.30 g, 10.01 mmol), O-methyl-hydroxylamine hydrochloride (1.67 g, 20.02 mmol) and NaOH (0.72 g, 18.00 mmol) in 1,4-dioxane (30 mL) and water (6 mL) was heated at 60° C. for 3 h. After this time, NaOH (0.72 g, 18.00 mmol) was added and the reaction mixture was heated for another 3 h. The volatiles were removed under reduced pressure. Saturated NaHCO3 solution (100 mL) was added to the residue, the mixture was extracted with EtOAc (3×25 mL). The combined organic extracts were washed with water (50 mL), brine (50 mL) and dried over Na2SO4. The solvent was removed under reduced pressure and the crude product was purified by flash column chromatography using gradient elution from CH2Cl2/EtOH (99:1) to CH2Cl2/EtOH (95:5) to yield 2.17 g (90%) of N-(4,6-bis-n-propylamino-[1,3,5]triazin-2-yl)-O-methyl-hydroxylamine (XLI). ESI-MS (m/z): 241 [M+H]+
