Chur to Interlaken Ost via Zürich and Bern is in fact the fastest way of getting there. Other alternatives involve more mountainous terrain and take longer. If you download the map from the link below, this might be apparent:
If it were me, I would consider doing the trip in the reverse direction as follows:
Day 1: Zürich to St. Moritz (overnight in St. Moritz)
Day 2: St. Moritz to Zermatt on the Glacier Express (overnight in Zermatt)
Day 3: Zermatt to Interlaken Ost. You could spend the morning and perhaps early afternoon in Zermatt before heading to Interlaken Ost.
Of course, if you have already booked your accommodation and prefer not to change it, or would lose money by doing so, this would not be an option.
