1099-misc box 3 for pipeline easement

Received 1099-misc with box 2 "royalties" and box 3 "other income".  Box 2, no problem.  However, Box 3 was for a Pipeline Easement. This should be a capital gain. The gain is much greater than my basis.  How do I move 1099-misc box 3 "other income" to schedule D so it will be taxed at the long-term gain rate.
