実験手順

To a solution of (-)-α-amino-4-hydroxybenzeneacetic acid (0.6 mole) in a minimum amount of concentrated hydrobromic acid at 35°-40° C. is added 50 ml of aqueous formaldehyde (35-37%) (0.6 mole). The addition of hydrogen bromide gas is begun. After 5-10 minutes, a solid begins to precipitate. Stirring is continued for 30 minutes. The title compound is collected and washed with ether and acetone.
