A neutron has valence quark content of udd and a proton has valence quark content of uud. So an antiproton has antiup and antidown quarks which can annihilate with up and down quarks in a neutron. They can’t fully annihilate each other; there will still be some quarks in the final state (probably in the form of pions).
