Try doing a ritual of some sort so she knows what is to come and is more accepting (I know that sounds all good but then theres reality of she does not want to do it). I use to take my son on a walk, sun or snow, it helped tire him out and I would let him know what we were going to do after naptime, such as paint, color, go to the park, have snack etc.
Also try creating a palat with a mat or blankets rather than putting her to bed, letting her pick her blanket, her area, outside of the bed where she can nap so it does not seems so permanent like bedtime. Good luck...
