실험 절차

To a solution of 1.00 g of 3-[(4-bromophenyl) methyl]-2-butyl-6-(1-hydroxy-1-methylethyl)-4(3H)-quinazolinone in 2.0 ml of DMF is added 0.438 g of t-butyldimethylsilyl chloride followed by 0.4 g of imidazole. The reaction mixture is stirred at room temperature for 18 hours and then diluted with water and extracted with ether. The combined ether extracts are dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by flash chromatography eluting with ethyl acetate/hexanes (1:5) to provide the desired product as a white solid.
