الإجراء التجريبي

6 g of L-phenylglycine or L-p-hydroxyphenylglycine were suspended in a mixture of 20 ml of 95% acetic acid and 0.2 ml (0.05 mole per mole of the L-amino acid used) of salicylaldehyde. The suspension was stirred at 100° C. for 2 hours. After the reaction, the mixture was cooled to room temperature, and the crystalline precipitates were collected by filtration and then washed with methanol. DL-phenylglycine or DL-p-hydroxyphenylglycine was thereby obtained. The results are shown in Table 17.
