実験手順

2-(2,3-Dihydro-2-oxo-3-phenyl-5-benzofuranyl)-1-(4-methylpiperazinyl-1-oxoethane was prepared according to the process described in Example 3, but using 4-methylpiperazine in Stage C. The latter compound was dissolved in a solution of DL-tartaric acid to form the corresponding salt, and then recrystallized in ethyl ether.
