Reference of 6705-33-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 6705-33-5 name is Pyrazin-2-ylmethanol, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a stirred solution pyrazin-2-ylmethanol (500 mg, 4.545 mmol) in DCM (20 ml) was added Dess-martin periodinane (2.89 g, 6.818 mmol) and stirred for 1 hr at RT. Reaction mass was diluted with DCM (100 ml) washed with saturated sodium bicarbonate solution (50 ml X 2) twice. DCM part was separated, dried over sodium sulfate, evaporated to dryness to get 300 mg crude, which was purified by column chromatography using 100-200 silica and 20% EtOAc in hexane as eluent to afford pyrazine-2-carbaldehyde (100 mg) as brown liquid.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Pyrazin-2-ylmethanol, and friends who are interested can also refer to it.
