Reaction Steps
Carnitine chloride (1.97 g; 0.01 moles) was dissolved in trifluoroacetic acid (10 cc). To the resulting solution 3-cyclopentanpropionyl chloride (1.60 g; 0.01 moles) was slowly added under stirring. The resulting mixture was kept under stirring at 45° C. overnight. The mixture was then cooled, acetone (40 ml) was added and the mixture was kept under stirring for 2 hours in ice. The precipitate thus formed was filtered off and to the filtrate ethyl ether was added. The white solid which precipitated was dissolved in ethanol-acetone (5:1) and once again precipitated with ether. M.P. 170°-172° C., yield 90%.
