try:
<make a copy of you data before runing the code >
Code:
awk '{print FILENAME,substr(FILENAME,1,match(FIENAME,"_")-1).txt}' *_*_*.txt |while read line1 line2
do
mv $line1 $line2
done

Code:
for i in *.txt
do
      mv "$i" "${i%%_2*}".txt.in
done

or
Code:
for i in *.txt
do
      mv "$i" "${i%_*_*}".txt.in
done

... or if you want to keep the date in the filename :

Code:
for i in *.txt
do
      mv "$i" "$i".in
done
