Procedure

To a solution of 2-Amino-3-(4-tert-butoxy-phenyl)-N-(2,2-diethoxy-ethyl)-N-(1H-indazol-7-ylmethyl)-propionamide in CH2Cl2 (50 mL) was added a solution of (3R)-3-(3-Benzyl-ureido)-hex-5-enoic acid (1.6 g, 6.1 mmol), EDCI (1.17 g, 1.2 eq), HOBt (0.93 g, 1.2 eq), DIEA (2.13 mL, 12.2 mmol) in CH2Cl2 (100 mL) stirred for 40 min. The reaction mixture was stirred at room temperature for 14 h, and then diluted with EtOAc, washed with water and brine. The organic layer was dried with Na2SO4 and concentrated in vacuo. The crude compound was used next step without further purification. MS ESI 727 (M+H), 749 (M+Na)
