Procedure

To a 20 mL flask equipped with stirring was added [3-oxo-1-(toluene-4-sulfonyl)-piperazin-2-yl]-acetic acid (104 mg, 0.33 mmol), 6-(1-piperidin-1-ylmethyl-vinyl)-1,2,3,4-tetrahydro-naphthalen-1(R)-ylamine (Step g, 90 mg, 0.33 mmol), EDC (Aldrich, 96 mg, 0.50 mmol), HOBt (Aldrich, 45 mg, 0.33 mmol), and CH2Cl2 (2 mL). The reaction mixture was stirred at RT overnight and diluted with CH2Cl2 (50 mL). The organic phase was washed with saturated NaHCO3 and brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude was purified by preparative TLC in 10% MeOH-CH2Cl2 to afford the title compound as a mixture of two diastereomers. MS (ESI): 565 (M+H)+.
