Narrative:

We were leveled at FL340 on our climb up to FL430; our filed altitude. The controller told us to climb to FL380 upon reaching besas intersection. She then gave us a re-route and I copied down the clearance. The new altitude of FL380 was set by the pilot flying and I confirmed it. While both of us were looking at the enroute charts to confirm the routing; we crossed besas intersection and did not climb to our new altitude of FL380. Just after crossing besas intersection; the controller asked us to 'say altitude.' I told her we were starting our climb up to FL380. She then canceled the clearance and re-cleared us to FL360 instead; due to conflicting traffic. Nothing more was said about the failure to climb and the flight continued normally. We allowed ourselves to get distracted by the new routing and forgot about the primary task of flying the aircraft. We should have delegated tasks and made sure someone was always monitoring the status of the aircraft.

Title: Distracted by programming a route change received coincident with a climb clearance which included a delay until an upcoming waypoint; the flight crew of a C750 failed to begin the climb as required and had to be re-cleared to a lower altitude due to conflicting traffic.
