Procedure
1.52 ml of 1 N sodium hydroxide are added to 420 mg (1.02 mmol) of 2-{[3-(3-methoxy-4-nitrobenzoyl)-2-methylindolizin-1-yl]oxy}ethyl acetate, a compound of Example 79, dissolved in 6 ml of dioxane, and the medium is stirred at room temperature for 6 hours. The reaction medium is poured over water and ethyl acetate. The organic phase is separated after settling out, washed with water, dried over sodium sulphate and concentrated under reduced pressure. 340 mg of an orange-coloured powder are obtained, which powder is used without further purification in the subsequent nitro reduction step.
