Procedure details

30 g of 2,4-difluorophenyl(4-piperidinyl)methanone hydrochloride obtained in step B) and 30 g of hydroxylamine hydrochloride were added to 50 ml of ethanol. 29.5 ml of N,N-dimethylethanolamine was added thereto dropwise while stirring at room temperature, and then the mixture was refluxed for 3 hours. The reaction mixture was cooled to room temperature, and the precipitated solid was filtered and dried to obtain 26.4 g of the title compound as a white crystal (yield: 96%).

Open Reaction Database (ORD)
Description
The Open Reaction Database (ORD) is an open-access schema and infrastructure for structuring and sharing organic reaction data, including a centralized data repository. The ORD schema supports conventional and emerging technologies, from benchtop reactions to automated high-throughput experiments and flow chemistry. Our vision is that a consistent data representation and infrastructure to support data sharing will enable downstream applications that will greatly improve the state of the art with respect to computer-aided synthesis planning, reaction prediction, and other predictive chemistry tasks.
