Participants

Reaction Steps

To a solution of 2-[({[(1-methyl-1H-imidazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyrimidin-4-amine (200 mg, 0.65 mmol) in 1,4-dioxane (10 mL) were sequentially added triethylamine (0.18 mL, 1.30 mmol) and chloroformic acid pentyl ester (0.38 mL, 2.60 mmol). After stirring at room temperature for 19 h, the mixture was concentrated in vacuo, diluted in ethyl acetate (50 mL), washed with water (20 mL), dried over MgSO4 and concentrated to dryness in vacuo. Purification on silica gel afforded pentyl{2-[({[(1-methyl-1H-imidazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyrimidin-4-yl}carbamate [26 mg, yield 9%; HPLC/MS: m/z=423 (M+H); log P(HCOOH)=2.66].
