Reaction Steps

To a mixture of 4-(1-{4-[2-(hydroxy)-3,3-dimethyl-butoxy]-3-methylphenyl}-1-ethylpropyl)-2-methylbenzoic acid, Example 1, (0.53 g, 1.29 mmol), 2-aminoethylmethylsulfone hydrochloride (0.21 g, 1.29 mmol), HOBt (0.19 g, 1.43 mmol), Et3N (0.72 mL, 5.19 mmol) and CH2Cl2 (10 mL) is added EDCI (0.249 g, 1.29 mmol) and stirred overnight. The reaction is diluted with CH2Cl2 (50 mL), washed with 1M HCl (2×30 mL), H2O (20 mL), satd NaHCO3 (2×20 mL), and brine (20 mL). The organic layer is MgSO4 dried, concentrated, and chromatographed (75% EtOAc/Hex) to give the title compound (0.51 g, 76%).
