    • For very large-scale preparations, a limiting step is the separation of meso-2b and d,l-2b by column chromatography. To overcome this problem, this mixture can be treated by acetaldehyde to form meso-3 and d,l-3. The aminal d,l-3 was selectively crystallized out of acetonitrile, and after hydrolysis under acidic conditions, d,l-2b was recovered and used for the separation of the d and l isomers (yield of d,l-2b isolated from a meso-2b and d,l-2b mixture on a 30 g scale: 79%).
