Ammonia → HCID 19425278, compound

Participants

Reaction Steps

N-(2-Fluoro-4-chloro-5-cyclopentyloxyphenyl)-3,4,5,6-tetrahydrophthalimide (1.00 g, 2.75 mmol) and tetrahydrofuran (20 ml) as a solvent were placed into a round bottom flask (50 cc), and an excess amount of 25% aqueous ammonia was poured into the mixture, followed by stirring for one hour at room temperature. After completion of the reaction, the solvent was distilled off under reduced pressure, and the precipitated crystals were isolated by filtration. The crystals were washed with hexane and dried to obtain N-(2-fluoro-4-chloro-5-cyclopentyloxyphenyl)-3,4,5,6-tetrahydrophthalamide as white crystals (0.400 g, 38.2% yield).
