    • A crystal of 2-amino-2-[2-[4-(3-benzyloxyphenylthio)-2- chlorophenyl]ethyl]-1,3-propanediol hydrochloride obtainable by a method comprising the steps of:
      (1) dissolving 2-amino-2-[2-[4-(3-benzyloxyphenyylthio)-2-chlorophenyl]ethyl]-1,3-propanediol in a mixed solvent comprising a solvent in which the compound in the form of the hydrochloride thereof is highly soluble and a solvent in which the compound in its hydrochloride is less soluble, to thus prepare a solution of 2-amino- 2-[2-[4-(3-benzyloxyphenylthio)-2-chlorophenyl]ethyl]-1,3-propanediol; and then
      (2) adding hydrochloric acid to said solution with stirring, to thus crystallize the hydrochloride of 2-amino-2-[2-[4-(3-benzyloxyphenylthio)-2-chloro-phenyl]ethyl]-1,3-propanediol, wherein the solvent in which the hydrochloride of the compound is highly soluble is selected from the group consisting of methanol, ethanol, propyl alcohol, isopropyl alcohol, butanol, t-butanol, acetonitrile and propionitrile; and wherein the solvent in which the hydrochloride of the compound is less soluble is selected from the group consisting of water, ethyl formate, ethyl acetate, propyl acetate, ethyl propionate, diethyl ether, diisopropyl ether and ethylene glycol dimethyl ether.
