Procedure

N-{5-[(1R)-2-Amino-1-hydroxyethyl]-2-hydroxyphenyl}methanesulfonamide (33.2 mg) was added to a solution of 1-{4-[(6-bromohexyl)oxy]butyl}-3-(cyclopentylsulfonyl)benzene (Example 1v.) (50 mg) in DMF (5 ml). The reaction mixture was treated with N,N-diisopropylethylamine (29.3 μl) and stirred at room temperature for 113 h. The reaction mixture was partitioned between EtOAc and water and the organic extracts were washed with ammonium chloride, dried (MgSO4) and concentrated in vacuo. The residue was purified by column DCM) to afford the title compound. LCMS RT=2.73 min 610(M+H)+
