Reaction Steps

To a solution of trifluoro-methanesulfonic acid 7-(piperidin-4-ylmethyl-propyl-amino)-5,6,7,8-tetrahydro-naphthalen-2-yl ester (200 μL of a 0.19 M solution in acetonitrile, 36 μmole) was added 220 μL of a 0.25 M solution of morpholine 4-carbonyl chloride in dichloromethane and 30 μL of DIEA. The solution was allowed to stir for 48 h at 25° C. under N2, and was then concentrated in vacuo. The final product was isolated by preparative RPHPLC (YMC Combiprep ODS-A column, 10-90% acetonitrile: water (0.1% TFA)) to afford trifluoro-methanesulfonic acid 7-{[1-(morpholine-4-carbonyl)-piperidin-4-ylmethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-yl ester (12.8 mg) 106[M+H]+=548.
