Reaction Steps
To a solution of S-aminoquinuclidine (0.086 g, 0.434 mmol) TEA (0.302 ml, 2.17 mmol), and anhydrous DMF (2.5 ml) was added 4-[((1S,2R)-1-(3,5-difluorobenzyl)-3-{[1-(3-ethylphenyl)cyclopropyl]amino}-2-hydroxypropyl)amino]-4-oxobutanoic acid (0.200 g, 0.434 mmol), EDC (0.125 g, 0.651 mmol), and HOBT (0.088 g, 0.651 mmol) under nitrogen, with stirring at 45° C. overnight. Reaction mixture was quenched with 10% sodium bicarbonate (aq.) then extracted with ethyl acetate then concentrated in vacuo, yielding product (0.093 g). Prep-HPLC yielded the product as its formate salt. (ES+: 569.3)
