214 mg of (+)-4-(2-methoxyethyl)-phenyl glycidyl ether were condensed with isopropylamine as in Example 2 to obtain 146 mg of (-)-metoprolol melting at 44-46° C. with [α]D25=- 5.00° (c=1.01 in ethanol). Optical purity (method as in Example 2) was determined to be 98%. Evaporation of the mother liquor yielded 9 mg of (-)-metoprolol of 97.5% optical purity.
