YieldReaction ConditionsOperation in experiment
59% With n-butyllithium; In tetrahydrofuran; hexane; at -78℃; for 0.5h; Step B: (3-[ten'-butyl(diphenyl)siIyl]oxy}phenyl)(lJHr-indazol-3-yl)methanone[0202] ; Indazole-3-(N-methoxy-N-methyl)amide (0.0244 mol) and l-Bromo-3- (tert-butyl diphenylsilyloxy)benzene (0.0244 mol) were dissolved in dry THF (144 mL, 0.17 M). The solution was vigorously stirred at -78 C. A solution of n-butyl lithium in hexane (2 equivalents of a 1.6 M solution, 0.0488 mol, 31 mL) was added very slowly EPO <DP n="66"/>(approximately 0.5 mL per minute). The reaction was stirred at -78 C for a half hour. The progress was monitored by TLC by quenching a small aliquot with 1-2 N aqueous HCl and eluting with ethyl acetate. In addition, the reaction was monitored with mass spec. When the reaction was complete, it was quenched with 1-2 N aqueous HCl and extracted with ethyl acetate. The product was purified by column chromatography. Hexane (100%) was used to remove the top spot, and hexane / ethyl acetate (50/50) was used to remove the product. The reaction gave 6.81g (0.0143 mol, 59% yield) of product as a waxy solid. MS (ESI) m/z [M+H]+ (477); MS (ESI) m/z [M-H]- (475);
