Abstrakt: 1-(5-{[(2R,3S)-2-({(1R)-1-[3,5-Bis(trifluoromethyl)phenyl]ethyl}oxy)-3-(4-fluorophenyl)morpholin-4-yl]methyl}-2H-1,2,3-triazol-4-yl)-N,N-dimethylmethanamine hydrochloride 3 is a high affinity, orally active, h-NK1 receptor antagonist with a long central duration of action and a solubility in water of >100 mg/mL. The construction of the 5-dimethylaminomethyl 1,2,3-triazol-4-yl unit, which incorporates the solubilizing group of 3, was accomplished by thermal rearrangement of a propargylic azide in the presence of dimethylamine. Compound 3 is highly effective in pre-clinical tests that are relevant to clinical efficacy in emesis and depression.
