Procedure

A mixture of 2-chloro-N-(4,6-bis-(n-propylamino)-[1,3,5]triazine (XXXIV) (1.65 g, 16.61 mmol), O-isopropyl-N-methyl-hydroxylamine hydrochloride (LXIII, 2.09 g, 16.61 mmol) and NaOH (0.66 g, 16.61 mmol) in 1,4-dioxane (50 mL) and water (5 mL) was heated at 100° C. for 16 h. The volatiles were then removed under reduced pressure. Saturated NaHCO3 solution (50 mL) was added to the residue and the mixture was extracted with EtOAc (3×50 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 N-(4,6-bis-propylamino-[1,3,5]triazin-2-yl)-O-isopropyl-N-methyl-hydroxylamine (LXIV, 1.93 g, 95%). ESI-MS (m/z): 283 [M+H]+.
