Reaction Steps

To a solution of enantiomer A of butyl 1-[(trans-4-tert-butylcyclohexyl)amino]indane-5-carboxylate, (41 mg, 0.11 mmol) in CH2CL2 (3 mL) was added (4-isopropylphenyl)acetic acid (98 mg, 0.55 mmol), EDC (105 mg, 0.55 mmol), HOBt (74 mg, 0.55 mmol) and DIEA (200 μL, 1.10 mmol). After stirring at room temperature for 18 h, the reaction mixture was poured into saturated aqueous NaHCO3 (10 mL) and extracted with EtOAc (20 mL). The organic layer was washed with brine (2×10 mL), dried over Na2SO4, filtered and concentrated. Chromatography (10% EtOAc in Hexane) gave butyl 1-{(trans-4-tert-butylcyclohexyl)[(4-isopropylphenyl)acetyl]amino}indane-5-carboxylate. HPLC/MS: m/z=532.3 (M+1), Rt=3.15 min.
