Sulfamide → HCID 19004203, compound

Participants

Reaction Steps

A solution of 1-(4-aminophenethyl)-4-(diphenylmethoxymethyl)piperidine (200 mg, 0.50 mmol) (see Example 21) and sulphamide (480 mg, 5.0 mmol) in dioxane (5 ml) was heated under reflux for 3 hours and evaporated. The residue was partitioned between ethyl acetate and 10% aqueous potassium carbonate solution and the layers separated. The aqueous layer was extracted into ethyl acetate and the combined organic layers were dried over magnesium sulphate and evaporated. The residue was purified by chromatography on silica using dichloromethane plus 0-4% methanol as eluant. Appropriate fractions were combined and evaporated and the residue triturated with diisopropyl ether. The resulting solid was collected, washed with diisopropyl ether and dried to give the title compound (100 mg) as a pale yellow solid, m.p. 172°-174° C., which was characterised by its 1H-NMR spectrum.
