Versuchsvorschrift
To a microwave vial was added 5-bromo-4-chloro-2-(2,5-dimethyl-1H-pyrrol-1-yl)-6-methylpyrimidine (4.95 g, 16.5 mmol) and hydrazine (0.57 ml, 18.1 mmol) hunig's base 95.74 ml, 32.9 mmol) and dimethyacetamide (24 ml) at R.T. After heating in the microwave for 30 mins at 100° C. The reaction mixture was concentrated under reduced pressure to dryness and the residue was trituarated with 1:1 ethyl acetate:methanol to obtain the desired product as a white solid weighted 2820 mg. The mother liquor was purified by column chromatography eluted with 30% EtOAc:hexane to give an additional batch of the desired product. Both lots were combined to give the titled compound as a white solid weighted 3620 mg 74%
