The reaction mixture was stirred at room temperature for 3 hours, concentrated in vacuo, poured into H2O (450 mL), and filtered to give a crude brown foam. Purification by flash column chromatography (silica, ether:petroleum ether 1:1) gave 6-(4-Chlorobenzoyi)-1-cyclopropylmethyl4-(3-trimethylsilanylethynyl-phenyl)-1 H-quinolin-2-one (3.47 g, 92%) as a yellow solid.
