Procedure

L-methionine (2.00 g, 13.4 mmol) was added to an MeOH solution of NaOMe (prepared with Na: 0.30 g, MeOH: 50 ml) at 0° C. and stirred. An MeOH solution (30 ml) of zinc acetate dihydrate (1.50 g) was then slowly dropwise added thereto at room temperature. After stirring for 3 hours, the precipitated crystal (in suspension) was recovered by filtration, washed with water, air dried, and then dried under a reduced pressure (5 mmHg, 80° C.).
