Narrative:
ILS-T approach to runway 9R. Approach control vectored us to intercept the localizer closer in than normal. While trying to catch the glide slope; the flight director went to altitude hold. At that point we got slow during the momentary level off. The autopilot was then disconnected in an attempt to try to catch the glide slope manually. As we approached 1;000 ft AGL; we still had not captured the glide slope and therefore were not established in a stable approach. A go around was executed and approach control vectored us around for a normal approach and landing. These vectors may have been acceptable under VMC; but the field was IMC; so I should not have accepted the vectors and stayed with the full published procedure to give us a more standard descent rate prior to intercepting the approach. As for getting slow; that was the result of the rushed procedure; but I should have caught it earlier and not let the airplane get below minimum maneuver speed for our configuration.
