Abstract

... It was found that temperature control was again critical in this process. ... The organic layer containing pyrazole 5 was then concentrated and diluted with THF, and the hydrolysis to pyrazole acid ... This procedure was scaled up in the pilot plant to deliver a total of 28.1 kg of pyrazole ...
