Versuchsvorschrift

Compound 9 (100 mg), 1-(cyclopropylmethyl)-N-methylpiperidine-4-amine (56.6 mg) and triethylamine (234 μL) were suspended in acetonitrile (2 mL). While the suspension was cooled with ice, a 50% propane phosphonic acid anhydride ethyl, acetate solution (273 mg) was added portionwise. The equipment used to add the 50% propane phosphonic acid anhydride ethyl acetate solution was thoroughly washed with acetonitrile (0.5 mL) and was stirred at room temperature (20 to 30° C.) overnight. Subsequently, the reaction mixture was concentrated under reduced pressure and the resulting residue was purified by amino-coated silica gel (Fuji Sylysia Chemical Ltd.; NH-DM1020) column chromatography (methylene chloride:methanol=30:1) to give 79 mg (52% yield) of the desired product as a pale yellow amorphous.
