It is an amino acid derivative, which can be prepared by reacting L-leucine with 9-FMOC-L-Leucinefluorenylmethyloxycarbonyl chloride. It has been reported in the literature that it can be used to prepare 9-fluorenylmethyloxycarbonyl chloride.Extraction with n-butyl acetate (80 ml) to remove excess 9-fluorenyl methoxycarbonyl chloride, the resulting aqueous phase was acidified with concentratedFMOC-L-Leucine hydrochloric acid to pH = 0.5 to 3.5, and then extracted with n-butyl acetate (80 ml), the resulting oil phase The Chemicalbook was washed with water to remove hydrochloric acid, and the oil phase was concentrated to remove the n-butylFMOC-L-Leucine acetate solvent. White crystals separated out, filtered and dried to obtain 2.46 g of Nα-9-fluorenylmethoxycarbonyl-L-leucine. The yield was 87.0%. Melting point : 151-15
