Reaction Steps

To a solution of 1.71 g (5 mmol) of 3-{N-[β-(3,4-diacetoxyphenyl)ethyl]}carbamoylpyridine (prepared like compound 8c), 1.41 g (10 mmol) of methyl iodide were added and the mixture was refluxed overnight under stirring. The acetone solution was then decanted from the insoluble oily residue. Ether was added to the acetone solution and the solid which separated was crystallized from acetone/ether. Yield, 1.9 g (78%) of yellow crystalline needles, m.p. 171°-173° C. U.V. (methanol) 215, 265 nm; NMR (D2O) δ 8.86-7.63 (ms, 4H, C5H4N+), 6.66 (bs, 3H, C6H3), 4.4 (s, 3H, --N+ --CH3), 3.50 (t, 2H, --N--CH2), 3.03 (t, 2H, CH2), 2.21 (bs, 6H, 2 COCH3). Anal. Calcd for C19H21IN2O5 : C, 47.12; H, 4.37; N, 5.78. Found: C, 47.23; H, 4.38; N, 5.78.
