Reaction Steps

A mixture of 0.72 g (1.7 mmol) 4-[1-Methyl-2,4-dioxo-6-(3-phenyl-prop-1-ynyl)-1,4-dihydro-2H-quinazolin-3-ylmethyl]-benzoic acid, 0.43 g (2.2 mmol) EDAC-HCl, 0.29 g (2.2 mmol) HOBT in 10 ml DMF is treated with 0.19 g (2.2 mmol) ethanolamine. The resulting mixture is stirred overnight at room temperature before diluting with water and extracting with 1:1 EtOAc/Et2O (2×). The combined organic extracts are washed with saturated aqueous NaCl (3×), dried (MgSO4). The resulting oil is dissolved in EtOAc and treated with saturated methanolic HCl. Concentration provided a solid which is triturated in EtOAc and filtered.
