Procedure

To the solution of 2-(2-(benzylcarbamoyl)-1-methylhydrazinyl)acetic acid (Compound VI-9) 299 mg (1.26 mmol) and (S)-2-amino-N—((S)-1,1-diethoxypropan-2-yl)-3-(4-hydroxy-2,6-dimethylphenyl)-N-(quinolin-8-ylmethyl)propanamide (Compound IV-9) 404 mg (0.84 mmol) in dichloromethane 5 ml and dimethylformamide 5 ml, 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride 305 mg (1.26 mmol) was added and stirred at room temperature for 24 hours. The reaction mixture was diluted with ethyl acetate 50 ml and washed with saturated sodium bicarbonate 50 ml, water 50 ml and brine 50 ml. The organic phase was dried with magnesium sulfate and filtered. The filtrate was concentrated in vacuo and the residue was purified on Buch silica gel column chromatography (chloroform:methanol=99:1 to 98:2) to obtain the title compound 298 mg (50%).
