Chemistry; Chem Sci/Eng
The residue is chromatographed on 110 g silica gel cartridge (30 to 50% ethyl acetate gradient in heptane) to afford 1-(1H-indol-5-yl)-ethanone [5.0g, 50.6%, Intermediate (17)] as colorless oil.
残留物用110 g矽膠萃取匣( 30到50%乙酸乙酯庚烷溶液梯度洗脱）层析，得到无色油状物1 - ( 1H -吲哚- 5 -基) -乙酮[ 5.0g, 50.6%,中间体( 17)]
"30 to 50% ethyl acetate gradient in heptane"可否译为"30到50%乙酸乙酯庚烷溶液梯度洗脱"
