Komponenten

Versuchsvorschrift

A mixture of methyl 2-isobutyl-4-oxo-3,4-dihydroquinazoline-7-carboxylate (55.8 mg, 0.21 mmol), KOH (0.3 g, 5.3 mmol) in water/dioxane (2 mL/5 mL) was stirred at room temperature for 1 h. The reaction mixture was poured into water (50 mL) and the solution was adjusted to pH to 4-5. The mixture was extracted with ethyl acetate (3×20 mL) and dried over Na2SO4. After filtration and concentration, the residue was purified by silica gel chromatography to give the desired product. MS (ESI): 246 (MH+).
