N-(3-amino-4-fluorophenyl)acetamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1.9 g (0.0113 mol) of 4-(N-acetylamino)-2-amino-1-fluorobenzene, 2.6 ml (2.78 g/0.0129 mol) of diethyl ethoxymethylenemalonate, and 4 ml of toluene is stirred at reflux for three hours, then allowed to cool to ambient temperature. The resulting precipitate is triturated with ether to give 3.29 g (84%) of title compound: at reflux for three hours The resulting precipitate is triturated with ether

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was prepared via {2-[3-(3-acetylamino-4-fluoro-phenyl)-3-cyclopentylmethyl-ureido]-thiazol-5-ylsulfanyl}-acetic acid ethyl ester in a similar manner as described for the synthesis of {2-[3-cyclopentylmethyl-3-(3,4-difluoro-phenyl)-ureido]-thiazol-4-yl}-acetic acid, using N-(3-amino-4-fluoro-phenyl)-acetamide, cyclopentanecarbaldehyde and (2-amino-thiazol-5-ylsulfanyl)acetic acid ethyl ester.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
