| abstract | (57) [Summary] [Objective] The objective is to obtain crystals of Nt-butyloxycarbonyl-3-cyclohexyl-L-alanine methyl ester. Composition: Oily Nt-butyloxycarbonyl-3 -Cyclohexyl-L-alanine methyl ester with n- Hexane 13.0 ml (6.8 wt%) and methanol 4.0 ml (2.6 wt%) were added at room temperature of about 25 ° C. and cooled to 4 ° C. with stirring, and the precipitated crystals were quickly separated by a centrifuge. Washed with 7 ml of cold n-hexane, The obtained crystals were air-dried and then dried under reduced pressure at 30 ° C. overnight to obtain 73.7 g of Nt-butyloxycarbonyl-3-cyclohexyl-L-alanine methyl ester crystals. |
