While cruising at FL410; the number 2 engine spooled back and the ENG FAIL alert was displayed. The Captain was flying and I was ready with the QRH. We started the drift down procedure. We were light that morning and the Engine Out Max Altitude was FL310. I requested a descent clearance to FL310; it was a slow descent. We started running the Engine Failure or Shutdown QRH. The engine indications we such that we attempted an engine restart. Following the QRH we accomplished the engine in flight start checklist. In order to do a crossbleed or windmill start we had to descend to FL240.We tried the windmill start first. No success. The second attempt was the crossbleed start; no success on that start either. While we were attempting the starts the Captain had already sent a message to Dispatch to see where they wanted us to divert to. The answer was [a nearby airport]. At that point we [advised ATC of the situation] and started our divert. I started setting up the approach; got the weather and NOTAMs; and ran the landing performance [calculations] for the first time in non-normal landing conditions flaps 15. We ran the one engine inoperative landing checklist. We landed without any further issues.
B737-700 First Officer reported diverting to a nearby alternate after the #2 engine failed in cruise flight at FL410.
