Extraction of caffeiene from tea?

Hello everyone, I am a student in need of your help! I am conducting a project for my chem cl where I extract caffeine from tea leaves. Its basic, I know. However, I have a problem I was hoping you all could help me solve. The experiment I am using calls for dichloromethane (a.k.a. DCM, methylene chloride, or CH2Cl2) and my teacher has run out of stock of it. I need it as a solving agent to extract the caffeine, so the question I am asking is; Is there a substitute I can use instead of dichloromethane, or, is there a way I can distill it? Thank-you and all answers are appreciated! (the experiemtn i am following is contained here http://www.scienceteacherprogram.org/chemistry/Paul00-2.html)
