Versuchsvorschrift

A suspension of 21 g (49.3 mmole) of 2-amino-4-(3,5-diacetylphenyl)amino-1,6-dimethylpyrimidinium iodide (compound No. 2, synthesized as described in section 6.1) in 1:1 methanol/water (750 mL) at 60° C. was treated with excess 2N NaOH with cooling to maintain about 60° C. An additional 200 mL of water was added and the mixture was cooled in ice and filtered to give 14.69 g 2-amino-4-(3,5-diacetylphenyl) imino-1,4-dihydro-1,6-dimethylpyrimidine as yellow crystals, mp 219-220°.
