Crossing pillar (200-300 mesh silicon gel column) purification and obtain compound 31.3 grams, productivity 5.4%, for red brown solid.TLC information: former
Material Rf=0.4, product Rf=0.7, developing solvent: oxolane: water=20:1.After measured, as it is shown in figure 1, its hydrogen modal data is
1H-NMR(DMSO；400MHZ)7.656(b,1H)8.44(d,1H)8.68(b,1H)9.55(b,1H).
Preparation process described in embodiment 1 is as follows:
Application test example
Kun Ming mice, body weight 20-22g, white mice is raised in the quiet environment that cleaning ventilation, light and shade circulate,
Ad lib is drunk water.Experiment is divided into two groups, often group 10, and every treated animal oral administration, wherein, matched group is Quetiapine 10mg/
Kg, test group are embodiment 1 gained final product compound 35mg/kg.After administration, every animal is placed in glass jar gently
(storing full water in cylinder), mice is swum 6 minutes, the dead time (second) accumulative in recording latter 4 minutes.Data acquisition SPSS12.0 unites
Meter software processes.Result of the test shows, the control group mice dead time is 159 ± 11 seconds, and the test group mice dead time is 98
± 11 seconds.Result illustrates, embodiment 1 gained compound 3 has antidepressant effect.
