1-Phenyl-5-methoxycarbonylisoquinoline → 1-Cyclobutylisoquinoline-5-acetonitrile

Participants

Reaction Steps

1-Amino-2-(2-hydroxymethylphenyl)ethane and cyclobutanecarbonyl chloride were successively reacted in the same way as in steps (b) and (c) of Example 12 to afford 1-cyclobutylcarbonylamino-2-(2-hydroxymethylphenyl)ethane as in oil. The product was successively reacted in the same way as in steps (d), (e), (f) and (g) of Example 12 to afford 1-cyclobutylisoquinoline-5-acetonitrile. The product was treated in the same way as in Example 3 to afford 1-cyclobutylisoquinoline-5-acetic acid having a decomposition point of 202.8° to 209.8° C.
