heptanimidamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Repeating the above procedure with 0.20 mole of heptanamidine, 0.15 mole 2-chloro-1,1-dimethoxy-3-butanone, 0.35 mole sodium acetate in 400 ml dioxane by refluxing for six hours, allowing to stand overnight at room temperature and work-up as above, affords a 42% yield of pure product, M.P. 104°-106° C. and 26% of impure product. For the pure sample: 1H-NMR (CDCl3) ppm (delta): 0.85 (t, 3H), 1.28 (m, 7H), 1.75 (m, 2H), 2.52 (s, 3H), 2.83 (t, 2H), 7.72 (s, 1H). by refluxing for six hours
