Reaction Steps

To a warm solution of (4E)-N-methyl-5-(5-pyrimidinyl)-4-penten-2-amine (258.6 mg, 1.46 mmol) in absolute ethanol (2.3 mL) was added galactaric acid (153.3 mg, 0.73 mmol). Water (0.8 mL) was added, and the solution was heated to near reflux until most of the solids dissolved. The solution was filtered through glass wool to remove a few white, insoluble particles, washing the filter plug with a warm solution of ethanol-water (4:1, v/v) (1.1 mL). The filtrate was diluted with ethanol (6.5 mL), cooled to ambient temperature, and further cooled at 5° C. for 48 h. The white precipitate was filtered, washed with cold ethanol, and vacuum dried at 40° C. for 18 h. The yield was 390.6 mg (94.8%) of a fluffy, white, crystalline powder, mp 164–167° C.
