14 EXAMPLE 14
EXAMPLE 14 An aqueous solution containing L-phenylglycine and D-phenylglycine amide, 295 g, obtained in Reference Example 3 was vacuum concentrated to 100 g. Thereafter, 190 g of n-butanol was added to the solution. The solution was vacuum concentrated to 110 g, 190 g of n-butanol was added again, and vacuum concentration was continued until 120 g of concentrate was finally obtained. After 30 g of n-butanol was added to the concentrate, the water content of the solution was 0.1% by mass. After this n-butanol solution was stirred at 70° C. for 1 hour, the solution was cooled and stirred at 20° C. for an additional 5 hours. Precipitated crystals were collected by suction filtration and 13.5 g (dry mass) of L-phenylglycine was obtained (yield 90%). The amount of D-phenylglycine amide contained in crystalline L-phenylglycine was 0.05% by mass.
