実験手順
0.798 g (2.69 mmol) of triphosgene diluted in 10 ml of dioxane is added, under an inert atmosphere at ambient temperature, to 1.3 g (3.84 mmol) of methyl 2-amino-5-[(1-methoxy-2-methylindolizin-3-yl)carbonyl]benzoate in 50 ml of dioxane. After stirring for 1 hour, 1.25 g (7.68 mmol) of N,N-dimethylglycinamide acetate and 2.68 ml (19.21 mmol) of triethylamine are added. The reaction medium is stirred overnight at ambient temperature and then hydrolysed with water. The aqueous phase is extracted with dichloromethane. The organic phase obtained is dried over sodium sulphate, filtered, and then concentrated under reduced pressure. 1.8 g of a yellow solid are obtained.
