Procedure
In a dry 3-necked, round bottomed flask, equipped with a magnetic stirrer, a thermometer, a nitrogen inlet tube and the dropping funnel containing the docosanoyl chloride solution, 12.59 g (96 mmol) of creatine is suspended, with stirring, in 100 ml of dry dichloromethane. To this suspension a catalytic amount (0.1 mmol) of pyridine is also added. The suspension is stirred in a dry ice and acetone bath to a temperature of between about −15° C. and 0° C. When the target temperature is reached the drop wise addition of docosanoyl chloride is commenced. Addition of docosanoyl chloride continues, with cooling and stirring, until all of the docosanoyl chloride is added, after which the reaction is allowed to warm to room temperature with constant stirring. The solution is then filtered to remove any remaining creatine, and the volatile dichloromethane and pyridine are removed under reduced pressure yielding 2-(3-dodecanoyl-1-methylguanidino)acetic acid.
