Syngoniums grow really quickly and so are really easy to propagate. The best way to propagate a mojito is to take a stem cutting with a node and a couple of leaves, and plant it in soil. Keep it humid, warm and bright but not direct sunlight, i.e. put it next to bright window, and in a propagation box or plastic bag. Keep it moist and refresh the air every two days. It should root well with two months. They grow really quickly and are very easy to get a successful propagation as long as you avoid rot.

we would let it callous over for a couple of hours after taking the cutting, as then the wounds will seal over and the chance of rot will be much lower.
