Are you beginning with the freebase? Honestly, the HCl isn't very water soluble either, so I wouldn't bother with this. Also, this is not a valid basis for a wiki article, so please read refer to the posting guidelines to make sure you post to the right place in the future.
Sort of. How much HCl should we add? We'll need to perform calculations in terms of moles, eventually deriving a desired volume of whatever solution of HCl you have on hand. And then you'll need to measure pH to make fine adjustments.
