Secrets of Methamphetamine Manufacture has instructions for synthesis of meth, amphetmine, MDMA and its analogues and i believe chemicals like 2C-i.
If you're going to get this book it could look suspicious to check out of a library, you could order it online and use a money order or some sort of gift card. There are some synthesis methods on the internet but be careful using these and look at a number of them before you attempt anything since they usually leave one or two small but crucial steps out.
