Participants

Reaction Steps

The compound is prepared as described in example X (step 4) with 800 mg (5.79 mmol) of 4,5-Diethyl-2-methyl-1H-imidazole (example XXVII, step 1), 2.75 g (17.36 mmol) of 4-fluorobenzoyl chloride and 1.93 g (19.10 mmol) of TEA in 15 ml acetonitrile. The crude intermediate (1.30 g, 2.58 mmol) is dissolved in 10 ml methanol under argon. 1.12 g (12.88 mmol) of morpholine are added dropwise to the solution. The mixture is refluxed for 10 minutes. The solvent is evaporated under argon and the residue is purified over silica (eluent: dichlormethane/methanol 50:1). The solvent is evaporated under vacuum to yield 572 mg (82.6% of th.).
