Reaction Steps

To a solution of {4-[(7-hydroxy-1,2,3,4-tetrahydro-naphthalen-2-yl)-propyl-amino]-piperidin-1-yl}-morpholin-4-yl-methanone (50 μmole in 420 μL DCM) was added 30 μL of DIEA followed by 220 μL of a 0.25M solution of 2-chlorobenzenesulfonyl chloride in THF. The solution was allowed to stir for 24 h at 25° C. under N2. 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 2-Chloro-benzenesulfonic acid 7-{[1-(morpholine4-carbonyl)-piperidin-4-yl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-yl ester 40 (5.1 mg), [M+H]+=690.
