الإجراء التجريبي

The amorphous compound obtained in Example 94 was subjected to alkaline hydrolysis, methylation with methyl iodide and potassium carbonate in dimethylformamide/tetrahydrofuran (1:1), and reflux with 3N hydrochloric acid, to obtain N-{1-(p-methoxybenzyl)-2-(4-oxopiperidino)ethyl}-N-methyl-5-isoquinolinesulfonamide in a colorless amorphous form.
