On February 28, 2002, Myers, Jason K.; Rogers, Bruce N.; Groppi, Vincent E., Jr.; Piotrowski, David W.; Bodnar, Alice L.; Jacobsen, Eric Jon; Corbett, Jeffrey W. published a patent.HPLC of Formula: 400715-69-7 The title of the patent was Preparation of N-quinuclidinyl-heteroaryl amides with nicotinic acetylcholine receptor binding activity for pharmaceutical use. And the patent contained the following:
N-quinuclidinyl-heteroaryl amides, such as I [R1 = H, alkyl, cycloalkyl, haloalkyl, aryl; R2 = H, benzyl, alkyl, haloalkyl, cycloalkyl, aryl; W = heteroaryl; X = O, S], were prepared for therapeutic use. Thus, the hydrochloride salt of quinuclidine carboxamide II was prepared in 57% yield by an amidation reaction of (3R)-3-aminoquinuclidine hydrochloride and 5-phenylthiophene-2-carboxylic acid using di-Ph chlorophosphate and Et3N in CH2Cl2 and DMF/H2O (5:1). The prepared quinuclidinyl amides were tested for nicotinic acetylcholine receptor binding activities. The experimental process involved the reaction of Ethyl 5-(3-chlorophenyl)oxazole-2-carboxylate(cas: 400715-69-7).HPLC of Formula: 400715-69-7
