L-Carnitine (1.61 g, 10 mmol) and acetylsalicylic acid (1.80 g, 10 mmol) were dissolved in ethanol (20 ml) and the solution concentrated in vacuo at about 40° C. till syrup consistence that on cooling crystallizes. The crystalline mass was triturated with acetone (50 ml), filtered, washed with acetone and dried in vacuo at room temperature. The yield of colorless crystals with m.p. 90-94° C. was 3.17 g (93%). The substance is water soluble, stable at ambient conditions.
