Using the crystal comprising (2R)-2-propyloctanoic acid and R)-(+)-1-phenylethylamine (6.8 g) produced in the second recrystallization and acetonitrile (102 mL), the same operation as in the second recrystallization was made to give the crystal comprising (2R)-2-propyloctanoic acid and (R)-(+)-1-phenylethylamine (6.0 g, 98.9% e.e.; yield 88%).
