Introduction of a new synthetic route about 87661-20-9

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 87661-20-9, name is tert-Butyl cyclopropanecarboxylate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C8H14O2

Example 71 (2S)-1-{1-[2-(4-Fluoro-3-methyl-phenyl)-5-methyl-oxazol-4-ylmethyl]-cyclopropylamino}-acetyl)-pyrrolidine-2-carbonitrile The title compound was prepared in analogy to example 60, steps A] to C] starting from 4-chloromethyl-5-methyl-2-(4-fluoro-3-methyl-phenyl)-oxazole and tert.butyl cyclopropanecarboxylate. The starting material could be prepared from 4-fluoro-3-methylbenzaldehyde and 2,3-butanedione oxime as described for benzaldehyde in Chem. Pharm. Bull. 1971, 19, 2050-2057. The title compound was obtained as a white gum. MS (ISP): 397.3 (MH+).

The synthetic route of 87661-20-9 has been constantly updated, and we look forward to future research findings.
