반응 단계

This compound was prepared from 4-Fluoro-N-methylbenzylamine which in turn was prepared from 4-Fluoro-N-methylbenzamide. Practical details are as follows: 4-Fluorobenzoyl chloride (25g) was added dropwise to a stirred aqueous solution of methylamine (40% w/v; 250 ml) at 0° C. over 30 min. The mixture was stirred for 12 h at room temperature, concentrated to half volume and the resulting crystalline precipitate was collected and recrystallized from water to furnish the N-methylbenzamide as colourless needles, (24.1 g; 89.1%), m.p. 131°-132° C.
