Ipswich boss Kieran McKenna reverted to the starting XI for their previous home game against Portsmouth, making six changes and opting to leave £10m former Norwich player Marcelino Nunez on the bench, while the Canaries brought Mirko Topic into midfield in place of Emiliano Marcondes.
Jim Magilton, the last Town manager to taste victory against their rivals back in 2009, was in the crowd at Portman Road and saw signs of a few early nerves as defenders Dara O'Shea and Jose Cordoba needlessly gave the ball away trying to pass forward into midfield, but neither error led to a scoring opportunity.
With Norwich pressing high, Ipswich struggled to impose themselves in the opening 20 minutes but a long ball then broke to Philogene who fired into the net, only for the goal to be disallowed because George Hirst had wrestled Harry Darling to the floor in the build-up.
Schwartau warmed Ipswich keeper Palmer's palms at the near post but the home side went in front when O'Shea headed down a corner and Kipre thrashed an unstoppable shot into the roof of the net on the half-volley.
The lead lasted just three minutes as Ipswich's attempt to clear a corner only reached Schwartau just outside the box and he had time to fire home his first Norwich goal since last December, with the help of a deflection.
Suddenly the tempo was frantic and Jens Cajuste found Hirst in the inside-right channel, but his angled shot was just off target, while Josh Sargent's left-footed effort lacked the power to trouble Palmer at the other end.
Philogene, though, had the final word of the half, spinning away from Pelle Mattsson and carrying the ball forward a few paces before burying his strike from distance into the net via the fingertips of Vladan Kovacevic - his fifth goal in four games.
