Reaction Steps

Fluoronitrobenzene (10.3 g, 0.073 mol) is dissolved in water and then potassium carbonate (12.1 g, 0.0876 mol) is added. 1-Methyl[1,4]diazepane (10 g, 0.0876 mol) is introduced and then the reaction medium is heated under reflux (≅100° C.) for 5 hours. The medium is cooled. A precipitate forms, which is filtered and washed with water. A yellow solid is recovered, which is dried at 45° C. in a vacuum oven (16.21 g, yield=94.5%).
