As a Dutch person, the pronunciation would make me want to write it as either Cilene or Silene. It turns out that the latter is the name of a type of plant in not only Dutch, but also English:

I guess most English speakers would pronounce the plant's name as sie-LEEN, though.
Cilene is also an actual name, by the way. The English Wikipedia has articles about two Brazilian women with the name, namely Cilene Rocha (b. 1967) and Cilene Victor (b. 1968).
