Triethylamine → 1-[2-(4-Ethyl-piperazin-1-yl)-pyridin-4-yl]-3-propyl-urea

Participants

Reaction Steps

A mixture of 20.6 mg (0.1 mmol) 2-(4-ethyl-piperazin-1-yl)-pyridin-4-ylamine, 15 mg (0.15 mmol) triethylamine and 9.4 mg (0.11 mmol) 1-isocyanato-propane in 1 ml dichloromethane was stirred at room temperature for 16 h. After evaporation the residue was taken up in 1 ml methanol/acetonitrile 1/1 and subjected to preparative HPLC purification on reversed phase eluting with a gradient of acetonitrile/water (0.05% triethylamine). The combined product fractions were evaporated to dryness to yield 7.2 mg (25%) of the title compound. (m/e): 292.3 (MH+; 100%).
