Reaction Steps

2-(R)-[(Morpholine-4-carbonyl)-amino]-3-phenylmethanesulfonyl-propionic acid (73 mg, 0.21 mmol, 1.0 eq.), N1-(4-Trifluoromethoxy-phenyl)-(S)-propane-1,2-diamine from Scheme 1a (48 mg, 0.21 mmol, 1.0 eq.), EDC (59 mg, 0.31 mmol, 1.5 eq.), and HOBT (38 mg, 0.25 mmol, 1.2 eq.) were dissolved in CH2Cl2 at room temperature. N-methylmorpholine (225 μL, 2.05 mmol, 10 eq.) was added via syringe and the reaction was monitored to completion by LC/MS. The solvent was evaporated and the reaction was purified by mass-directed HPLC and provided 44 mg (0.06 mmol, 31%) of a off-white solid as a mono-TFA salt: HPLC-MS calcd. for C25H31F3N4O6S (M+H+) 573.2, found 573.3.
