実験手順
Reaction of 4-chloro-5-sulfamoylphthalimide (5.21 g., 0.02 mole) and 4-amino-1-(4-methoxybenzyl)piperidine (4.5 g., 0.02 mole) in 80 ml. of n-pentanol according to the procedure of Example 1(a) afforded the crude 1,3-dioxoisoindole product purified by chromatography (silica gel, ethyl acetate-n-hexane) to yield 2.88 g. (31%) of 6-chloro-2,3-dihydro-2-[1-[(4-methoxyphenyl)methyl]-4-piperidinyl]-1,3-dioxo-1H-isoindole-5-sulfonamide. The NMR spectral data was consistent for the compound used without further purification below.
