Reaction Steps
Optimization experiments were performed by varying certain parameters of the reaction scheme in Example 1, as described below. A 1.5 mole equivalent of acetyl chloride was added dropwise to anhydrous ethanol to generate the acidified ethanol. Creatine monohydrate was added to the acidified ethanol at a ratio of 1 g:6 ml of ethanol and the reaction medium was heated to 37° C. for 20 hours. The reaction medium was then allowed to cool to 30° C. prior to filtration and the product (filter cake) was washed with ethanol chilled to 0° C. The amount of ethanol used in the wash was on a 1:1 w/v (g/ml) basis with the quantity of creatine monohydrate employed as the starting material. This reaction scheme yielded an 83 to 86% conversion of creatine monohydrate to CEE HCl.
