A suspension of 4-formyl-2,6-dimethoxyphenyl β-D-galactopyranoside (0.19 g, 0.55 mmol), 1,2-dimethylquinolinium iodide (0.16 g, 0.55 mmol) in ethanol (20 ml) containing ammonium acetate (0.13 g, 1.7 mmol) was stirred at about 60° C. for 5 h. The dark orange precipitate which formed during the reaction was then filtered off and washed with ethanol followed by acetone to give (22c)(0.2 g, 86%) as an orange powder.
