  • Patent number: 5455350
    Abstract: (C.sub.1 -C.sub.3)Alkyl-4,6,7,8,9,9a-hexahydro-2H,3H-pyrido[1,2-a]pyrazin-1-one-7-c arboxylate esters, important precursors to certain bis-aza-bicyclic anxiolytics, can be prepared from di(C.sub.1 -C.sub.3)alkyl cis-piperidine-2,5-dicarboxylate starting material by a new process via a new class of intermediates, di(C.sub.1 -C.sub.3)alkyl cis-N-(2-(phthalimido)ethyl)piperidine-2,5-dicarboxylates. In the process, the starting material is reacted with either 2-(phthalimido)ethyl triflate or 2-(phthalimido)acetaldehyde to form the new intermediate, which can then be cyclized to the aforementioned precursor.

  • Patent number: 5399678
    Abstract: A simplified method for making the chloromethyl ester of sulbactam in which the tetraalkylammonium sulbactam salt is not dried and isolated prior to alkylation. The method comprises reacting a tetraalkylammonium salt and a sulbactam salt in an aqueous solution to form an aqueous solution of tetraalkylammonium sulbactam. The tetraalkylammonium sulbactam is extracted into bromochloromethane or iodochloromethane, and water is removed from the organic layer to enhance the formation of the chloromethyl ester of sulbactam. The tetraalkylammonium sulbactam is reacted with bromochloromethane or iodochloromethane in the organic layer to form the chloromethyl ester of sulbactam.

  • Patent number: 5294744
    Abstract: A novel two-step reaction process for preparing 5-substituted-2-methoxybenzaldehyde compounds is disclosed wherein the substituent group is either isopropyl or trifluoromethoxy. The process involves (1) reacting a corresponding 4-substituted phenol compound with dimethyl carbonate in the presence of a tertiary-amine base to form the corresponding 4-substituted anisole compound, and (2) thereafter subjecting the latter intermediate product obtained in the first step to aromatic C-formylation on the ring with hexamethylenetetramine in the presence of trifluoroacetic acid, followed by hydrolysis, to ultimately yield the desired aldehyde compound. The two aromatic aldehyde compounds so obtained, viz., 2-methoxy-5-trifluoromethoxybenzaldehyde and 2-methoxy-5-isopropylbenzaldehyde, are known to be useful as intermediates that specifically lead to (2S,3S)-cis-3-(2-methoxy-5-trifluoromethoxybenzyl)amino-2-phenylpiperidine and (2S,3S)-cis-2-(diphenylmethyl)-N-[(2-methoxy-5-isopropylphenyl)methyl]-1-a zabicyclo[2.2.
