Ethyl formate → 1-Allyl-3-phenyl-5-(3-trifluoromethylphenyl)-4-piperidinone

Participants

Reaction Steps

Twenty g. of 1-phenyl-3-(3-trifluoromethylphenyl)-2-propanone was reacted with ethyl formate and allylamine hydrochloride as described in Examples 1-3 to obtain 10.8 g. of 1-allyl-3-phenyl-5-(3-trifluoromethylphenyl)-4(1H)-pyridinone, which was reacted with 2 g. of lithium aluminum hydride as described in Examples 1-3. The reaction mixture was worked up and chromatographed as described in the examples above to obtain 1.2 g. of the products of Examples 33 and 34 as a mixture. The compounds were identified by mass spectroscopy, which showed an indicated molecular weight of 357. A yield of 1.0 g. of the compound of Example 35 was obtained, which showed a mass spectroscopy molecular weight of 359.
