Procedure

To a solution of 3-amino-4-(3,5-difluoro-phenyl)-1-(7-ethyl-1,2,3,4-tetrahydro-naphthalen-1-ylamino)-butan-2-ol (0.240 g, 0.64 mmol), triethylamine (0.268 mL, 1.92 mmol), and chloroform (3 mL) was added glutaric anhydride (0.073 g, 0.64 mmol) and reaction was stirred overnight at 60° C. Reaction was washed with 1N HCl, 10% NaHCO3, brine, dried over MgSO4, filtered, concentrated in vacuo to give 5-[((1S,2R)-1-(3,5-difluorobenzyl)-3-{[(1S)-7-ethyl-1,2,3,4-tetrahydronaphthalen-1-yl]amino}-2-hydroxypropyl)amino]-5-oxopentanoic acid (100 mg). Purified via prep-HPLC. 1H NMR (400 MHz, CD3OD) δ 1.26 (t, J=8 Hz, 3H), 1.73 (m, 2H), 1.89 (m, 1H), 2.01 (m, 1H), 2.17 (m, 6H), 2.68 (d, J=8 Hz, 2H), 2.93 (d, J=6 Hz, 1H), 3.02 (m, 1H), 3.30 (m, 2H), 3.88 (m, 1H), 4.09 (m, 1H), 4.57 (m, 1H), 6.79 (m, 1H), 6.88 (m, 3H), 6.93 (d, J=6 Hz, 1H), 7.20 (m, 2H), 7.31 (s, 1H); OAMS: ES+ 488.9 ES− 486.9
