I doubt that the building is being demolished but I'll take a ride over there and check on it later today. The building in question dates back to 1936 when the station was WNBC (New Britain Connecticut, not National Broadcasting Company.) The building still houses the xmtr and I don't see any applications on file with the FCC to move the xmtr and/or the towers.
The studios and offices from it's Top Forty format in the 60's and 70's were a pre-fab building placed in front of the brick xmtr building. That pre-fab was dismantled and sold when Rt 175 was widened sometime in the early 80's (I think.) WPOP then moved to new studios about 3 miles east of the xmtr.
The land surrounding the xmtr building is all wetlands with a stream flowing between the two towers. If anyone like CCSU wanted to build something on that land they would face some serious environmental issues. And I haven't heard anything about that.
