You have to go to the base of the Hokage mountain and talk to the frog and collect the chakra fragments (Training field or the forest of dead trees have a lot of them) Once you get 1,000 points (check in the pause menu), talk to the frog again. You then have to collect another 5,000. After that, talk to the frog once more and he will tell you to find a special chakra fragment. This fragment opens a mob battle which you must complete. Once you have completed it, go to the ninja timeline and the Kabuto boss battle should be there.
