実験手順
Following a procedure similar to that described in Example 1, but using 2.53 g of 2-{2-[3,4-bis(methoxycarbonyl)phenoxy]-1-methylethyl}amino-1-(3-chlorophenyl)ethanol (prepared as described in Preparation 20), 0.91 g of lithium aluminum hydride and 100 ml of dry tetrahydrofuran, and then purifying the reaction product by column chromatography through silica gel, using a 5:1 by volume mixture of ethyl acetate and ethanol as the eluent, 1.04 g of the title compound were obtained having an Rf=0.37 (thin layer chromatography over silica gel, using a 5:1 by volume mixture of ethyl acetate and ethanol as the developing solvent).
後処理
- custompurifying the reaction product by column chromatography through silica gel
- additionby volume mixture of ethyl acetate and ethanol as the eluent
