This would not qualify as "Kitchen Chemisty", but it is do able if you're a skilled chemist with the appropriate knowledge and equipment. You would need proper equipment and skills to handle corrosive and dangerous chemicals and chemical reactions. For example, when producing 2c-b, you would need to be able to handle elemental bromine. Bromine is highly toxic and extremely reactive. For 2c-i you would need to handle pure iodine, which is corrosive and poisonous.
