Participants

Reaction Steps

Heat a mixture of N-ethyl-2-fluoro-N-(1-methyl-piperidin-4-yl)-benzene-1,3-diamine (Preparation 27) and 2-chloro-4-fluorobenzoyl chloride (23 mg) in 1,4-dioxane (5 mL) at reflux for 1 hour. Dilute with methanol (5 mL), load on a SCX column (10 g), wash with methanol, elute the product with 2M NH3 in methanol, evaporate to give the title compound: mass spectrum (electric spray) m/z=408 (M+1). Purify further by HPLC to give the di-trifluoroacetic acid salt.
