Procedure

1.8 g (9.8 mmoles) of copper(II) acetate are dissolved in 100 ml of hot methanol and a solution of 1.5 g (20 mmoles) of glycine in 50 ml of methanol is added with stirring to the resulting solution. The solution turns cloudy under the effect of precipitated product. After stirring for 2 hours at a falling temperature, the product precipitated is filtered off and dried. Yield: 2.5 g (96% of the theoretical), Mp.:>210° C.
