Procedure
Method 1 is a method in which after (2S)-3-(3,4-bis((2-(benzoyloxy)-2-methylpropanoyl)oxy)phenyl)-2-((tert-butoxycarbonyl)amino)propanoic acid is subjected to a deprotection reaction using p-toluenesulfonic acid, a solvate of (2S)-2-amino-3-(3,4-bis((2-(benzoyloxy)-2-methylpropanoyl)oxy)phenyl)propanoic acid tosylate is produced without performing an isolation operation, followed by drying by heating under reduced pressure, whereby a type A crystal is produced.
