实验过程

[1-[2-[(Methylsulphonyl)methylamino]ethyl]-4-piperidinyl]methyl[2-(3-methyl-1,2,4-oxadiazol-5-yl)phenyl]carbamate (55 mg) was dissolved in boiling ethyl acetate (1 ml) and maleic acid (17 mg) in hot ethyl acetate (1 ml) added. White crystals precipitated. These were filtered and dried under vacuum to give the title compound (51 mg), as a white powder, m.p. 170°-172°
