2-Chloro-3-formylpyridine (2-chloronicotinaldehyde) was obtained by reduction of 2-chloro-3-cyanopyridine by Raney nickel and formic acid (3 1); this intermediate is inaccessible by the above N-oxidation route (peroxyacid oxidation of 3-formylpyridine yields pyridine-N-oxide 3-carboxylic acid). In the synthesis of the parent 1 from 2-chloro-3-formylpyridine, the yield was prejudiced by the formation

The present invention provides a pyrrolidine compound of General Formula (1)
or a salt thereof, wherein R
101
and R
102
are each independently a phenyl group or a pyridyl group, the phenyl group or the pyridyl group may have one or more substituents selected from halogen atoms and lower alkyl groups optionally substituted with one or more halogen atoms, etc. The pyrrolidine compound or a salt thereof of the present invention is usable to produce a pharmaceutical preparation having a wider therapeutic spectrum and being capable of exhibiting sufficient therapeutic effects after short-term administration.
