Reaction Steps

1-cyclopentyl-6-oxo-5-(pyridin-2-yl)-1,6-dihydropyridine-3-carboxylic acid (0.0743 g, 0.261 mmol) was added to a vial followed by DMF (1 mL). HATU (0.15 g, 0.39 mmol) was added and the mixture was stirred for 5 minutes. 4-((2R,3S)-3-amino-2-hydroxy-4-phenylbutylamino)-6-methoxy-2,2-dimethyl-3,4-dihydronaphthalen-1(2H)-one (0.100 g, 0.26 mmol) was added followed by the addition of diisopropylethylamine (0.18 ml, 1.0 mmol). Reaction was allowed to stir at RT. After 2 hours, reaction the crude reaction mixture was purified using the Gilson. The solvent was evaporated to provide the title compound as a white solid. MS m/z: 649.6 (M+1).
