partitioning - Allocate free space on a partition inside an extended

• /dev/sda2 - EXT4 - 136GB of free space
  
  
  
  
  
  • /dev/sda3 Extended
  
  
  • /dev/sda5 - ext4 - my ubuntu partition
  
  
  • /dev/sda6 linux swamp
  
  

I need to put those 136GB from /dev/sda2 into /dev/sda5, but apparently, because they are separate by the extended partition I cannot allocate the freespace.

Do you guys know how can I do it without formating?
