In water(30 mL) were mixed ethyl 3-amino-4-pentynoate hydrochloride (258.3 mg, 1.5 mmoles), 30.6 mg (3.95 units) immobilized penicillin G amidohydrolase [Rohm-Pharma] and ethyl phenylacetate (205.7 mg, 1.25 mmoles). The initial pH (3.48) was adjusted to pH 6 with N NaOH (0.5 N) before addition of the ethyl phenylacetate. After 3 hours, an additional 0.9 mmole ethyl phenylacetate was added. This suspension was stirred vigorously at room temperature for six hours. Periodically, 1 mL samples were taken and diluted with acetonitrile and analyzed by reversed phase HPLC.
