Procedure
To a solution of 4-fluorophenylethylamine (1.0 equivalent) in dried THF was added Hunig's base (DIEA) (1 equivalent). The mixture was then stirred for 3 minutes at 0° C. Thereafter, a solution of chloroacetylchloride (1.0 equivalent) in THF was added via a syringe over a period of 7 minutes. The reaction mixture was then stirred at room temperature for 1 hour after which time the reaction mixture was condensed in vacuo, quenched with water, extracted with ethyl acetate (3×) and dried over Na2SO4. After concentration in vacuo, compound 1 shown above was obtained, which was carried on further without further purification. LC/MS=M+H 216.1 at 2.18 minutes.
