Reaction Conditions:
with ammonium hydroxide in 1,4-dioxane at 100 - 110;Sealed tube;Large scale;
Steps:
5.5 Example 5 Synthesis of Compound XIV
5.5 1.2 kg of compound XIII was added to a 50 L pressurized reactor, followed by 6.0 L of 1,4-dioxane and 6.0 L of aqueous ammonia. The temperature was raised to 100 to 110 ° C, and the reflux reaction was sealed for 6 to 8 hours.After the reaction is completed, the heating is turned off. It was concentrated to dryness under reduced pressure at 60 ° C, and was added once with 3.0 L of isopropyl alcohol. The crude product was concentrated to dryness, and 3.0 L of ethanol was added and beaten for 30 minutes.Filtration and drying of the filter cake gave 1.05 kg of compound XIV as a yellow solid product with a purity of 95.2% and a yield of 96.3%.
