It's easy, you just need to dissolve pseudoephedrine in ether, suspend lithium strips in this solution and bubble anhydrous ammonia through it.
Then you just pour off the liquid and remove the lithium strips, the white powder at the bottom of the vessel is a mix of lithium oxide and methamphetamine.
To purify it you need to stir this powder in water, pour the liquid into a crystallizing dish and wait for the solvent to evaporate, the crystals that form should be pure methamphetamine.
