@WillD Hello sir, I'm having trouble getting 2-methoxybenzaldehyde for step 4, can it be replaced with 4-methoxybenzaldehyde or is there a recommendation for another compound?

in scheme 4, how does it mean to treat with sufficient ammonium hydroxide and a saturated solution of NH4Cl until the precipitate dissolves. and how much weight is needed?
How do you make methamphetamine HCL from pseudoephendrine into clear crystals and not powder?
Does it have to be re-crystallized with ethanol like in the video?
