Cyclohexylmethylmagnesium bromide solution (1.77 ml; 885 μM of 0.5M solution in THF) was added dropwise to a solution of 5-benzyloxy-2-methanesulfonyl-1-methyl-6-oxo-1,6-dihydro-pyrimidine-4-carboxylic acid methyl ester (0.26 g; 738 μM) in THF (10 ml). After stirring at room temperature for 1 h, the reaction mixture was quenched by the addition of saturated ammonium chloride solution. The product was extracted into EtOAc, washed with brine, dried (Na2SO4) and evaporated to dryness under reduced pressure to give the title product as a colourless oil (0.040 g; 70%). LCMS: m/z=367 (MH+).
