Benzenemethanamine, 3,4-dimethyl- → 2-Amino-4-(4,5-dihydro-furan-2-yl)-6-(3,4-dimethyl-benzylamino)-pyrimidine-5-carbonitrile

Participants

Reaction Steps

To a stirred suspension of 250 mg (0.74 mmol) trifluoromethanesulfonic acid 2-amino-5-cyano-6-(4,5-dihydro-furan-2-yl)-pyrimidin-4-yl ester in 10 ml DME was added 0.20 g (1.49 mmol) 3,4-dimethylbenzylamine and the mixture stirred at room temperature for 1 hour. The reaction mixture was then partitioned between water and ethyl acetate and the organic phase was dried over sodium sulfate and concentrated in vacuo. Chromatography (ethyl acetate) followed by trituration in ether/hexane afforded 35 mg (15%) 2-amino-4-(4,5-dihydro-furan-2-yl)-6-(3,4-dimethyl-benzylamino)-pyrimidine-5-carbonitrile as a white crystalline solid. ES-MS m/e (%): 322 (M+H+, 100).
