Procedure

6-{1-[4-(3,3-Dimethyl-2-oxo-butoxy)-3-methyl-phenyl]-1-ethyl-propyl}-benzo[b]thiophene-2-carboxylic acid (290 mg, 0.642 mmol) in CH2Cl2 (5.0 mL) is treated with DMAP (235 mg, 1.93 mmol) and EDC (184 mg, 0.962 mmol). The mixture is stirred for 15 min at RT, and dimethylamine hydrochloride (78 mg, 0.962 mmol) is added. The reaction is stirred for 18 h and quenched with aqueous NH4Cl (5.0 mL). The organic layer is loaded onto a silica gel column and purified with 50% EtOAc/Hex to afford the title compound (280 mg, 91%).
