Reaction Steps
4-Methylphenylmagnesium bromide (1.64 mL, 1.0 M in ether) was added all at once via syringe to a well-stirred solution of 1-n-butyl-3-methyl-1,2,4-triazin-6-one (178 mg, 1.06 mmol) in ether (9.85 mL) under N2 at room temperature. After stirring the resulting mixture overnight, saturated aqueous NH4Cl (10 mL) and ethyl acetate (10 mL) were added, the organic phase was separated, and the aqueous layer was extracted once more with ethyl acetate. The combined organic layers were dried over Na2SO4 and evaporated to dryness. The crude product was purified by flash chromatography on silica gel (5 g, 4:1 hexanes:ethyl acetate) to afford Compound 22 as a tan solid (236 mg, 86% yield).
