Procedure
15.5 g of compound (12) (100 mmole), 1.5 g (50 mmole) paraformaldehyde and 4.1 g (50 mmole) dimethylamine hydrochloride were stirred for 25 minutes in 30 ml acetic acid in a bath at 105° C. The acetic acid was distilled off under vacuum, and the residue was dissolved in 110 ml 2-butanone. Compound (13) was obtained in a yield of 77% theoretical, melting point 125° C.-127° C.
