Potassium Carbonate → HCID 23326339, compound

Participants

Reaction Steps

To a suspension of potassium carbonate (6.0 g) in acetone (25 ml) was added triethylamine (1.5 ml) and 2-propyn-1-amine (2.35 g, 4.25×10-2 mole). 1,5-Difluoro-2,4-dinitrobenzene (10.00 g, 4.90×10-2 mole) was added and the reaction mixture was stirred at room temperature for 24 hours. The mixture was poured into excess water and filtered. The resulting dark solid was chromatographed on a silica column, eluting with benzene, and recrystallized from benzene to afford yellow crystals; m.p. 113°-115° C. Yield: 8.33 g (82%). I.R. (KBr): 3340 (NH), 3280 (CH), 1615, 1260 (Ar-NO2) and 1210 cm-1 (Ar-F).
