Participants

Reaction Steps

1.8 ml (12.92 mmol) of triethylamine are added, at ambient temperature under an inert atmosphere, to 1.7 g (10.77 mmol) of 1-methoxy-2-methylindolizine in 15 ml of dichloroethane, followed, dropwise, by 2.2 g (11.85 mmol) of 4-nitrobenzoic acid chloride. The reaction medium is stirred for 30 minutes at ambient temperature, hydrolysed with a saturated aqueous solution of sodium hydrogen carbonate and then extracted with dichloromethane. The organic phase is washed with a saturated aqueous solution of sodium chloride, dried over sodium sulphate, and then concentrated under reduced pressure. The residue obtained is washed with diethyl ether. 3 g of an orange solid are obtained.
