実験手順

A solution of ethyl 2-(3-acetoxy-1-chloro-2-(2-hydroxyethoxy)propan-2-yl)-5-hydroxy-6-oxo-1,6-dihydropyrimidine-4-carboxylate (2.322 g, 6.13 mmol) in tetrahydrofuran (100 mL) was treated with methane sulfonylchloride (2.11 g, 18.4 mmol) and Et3N (2.25 g, 22 mmol) and then heated (60° C., oil bath) for 3 hrs. Solvent was removed in-vacuo and the crude product was dissolved in ethyl acetate (100 mL), then washed with water (2×50 mL). The organic solution was dried (Na2SO4), filtered and concentrated in-vacuo to give the title compound as a viscous amber oil which was used immediately in the following reaction.
