Methyl 4-methoxyacetoacetate → HCID 178494553, compound

Participants

Reaction Steps

To a solution of methyl 4-methoxy-3-oxobutanoate (3.54 mL, 26.5 mmol) in methanol (30 ml) was added formamidine acetate (3.07 g, 29.2 mmol) and sodium methoxide (13 mL, 58.4 mmol). The mixture was then heated to reflux for 18 hours and cooled to ambient temperature, then concentrated. The residue was taken up in water and the pH adjusted to 7 with 1N HCl. The aqueous mixture was extracted with chloroform. The combined organic layers were dried over magnesium sulfate, filtered and concentrated to afford 6-(methoxymethyl)pyrimidin-4-ol (1.38 g, 9.85 mmol, 37.1% yield). MS (LC/MS) R.T.=0.19; [M+H]+=141.20.
