4.2 0.149 g of 12, 0.112 g of 2-amino-5-fluoropyridine 4, 0.209 g of 2-(2-formyl-3-methoxyphenoxy)acetamide 3, 0.286 ml of triethylamine and, dropwise, 2.5 ml of T3P® [=propylphosphonic anhydride (50% solution in ethyl acetate)] are introduced successively into a flask with ice-cooling and under an inert gas. The reaction mixture is stirred at 100° C. for 7 h. The mixture is subsequently subjected to conventional work-up, giving 0.2 g (40%) of “A1”.
