実験手順

A solution of 2-{1-[4-(2-Amino-ethyl)-2-p-tolyl-imidazol-1-yl]-2-methyl-propyl}-3-benzyl-7-chloro-3H-quinazolin-4-one (181 mg, 0.343 mmol), potassium carbonate (47 mg., 0.343 mmol), and tert-butyl bromoacetate (67 mg., 0.343 mmol) in DMF (2.0 mL) was stirred at room temperature for 4.5 h. The reaction was diluted with water and the resulting white precipitate was filtered and purified by flash chromatography (silica gel, 95:5 methylene chloride:methanol) to provide the title compound as a white solid (109 mg., 50%). MS(ES+) m/e 640 [M+H]+.

後処理

  1. filtrationthe resulting white precipitate was filtered
  2. custompurified by flash chromatography (silica gel, 95:5 methylene chloride:methanol)
