Versuchsvorschrift

Compound 9 (74.74 g), 1-benzyl-N-methylpiperidine-4-amine (66.78 g: 1.3 eq.) and triethylamine (127.20 g: 5 eq.) were suspended in acetonitrile (800 mL). While the suspension was cooled on ice, a 50% propanephosphonic acid anhydride ethyl acetate solution (191.99 g) was added portionwise. The equipment used to add 50% propanephosphonic acid anhydride ethyl acetate solution was thoroughly washed with acetonitrile (192 mL) and stirred at room temperature (20 to 30° C.) overnight. Subsequently, the mixture was concentrated under reduced pressure. To the resulting residue, chloroform (250 mL) and a saturated aqueous sodium bicarbonate solution (140 mL) were sequentially added and the mixture was transferred to a separation funnel. The reaction container was thoroughly washed with chloroform (175 mL) and separation was performed. Once the organic layer was separated, chloroform (175 mL) was added to the aqueous layer and separation was performed again. The collected organic layer was dried over magnesium sulfate and was suction-filtered. The filtrate was evaporated under reduced pressure to give 183.27 g of the crude desired product of Compound 30 as a yellow amorphous.
