Procedure

To a vial containing 4-((3,3-dimethylcyclobutyl)(quinolin-3-ylamino)methyl)benzoic acid (14.0 mg, 0.0390 mmol) was added 3-aminopropionic acid ethyl ester hydrochloric (6.60 mg, 0.0430 mmol), 1-Hydroxy-7-azabenzotriazole (6.40 mg, 0.0470 mmol) and 1-ethyl-3-(3-dimethylamino propyl)carbodiimide hydrochloride (9.00 mg, 0.0470 mmol). Anhydrous methylene chloride (0.390 mL) was added followed by triethylamine (0.007 mL, 0.0510 mmol). After 18 h, the reaction was diluted with methylene chloride and quenched with a saturated solution of ammonium chloride. The aqueous layer was extracted three times with methylene chloride. The combined organic layers were dried with sodium sulfate, filtered, and concentrated to give 26.0 mg of crude material. Purification by column chromatography (0-70% ethyl acetate in heptane) provided ethyl 3-(4-((3,3-dimethylcyclobutyl)(quinolin-3-ylamino)methyl)benzamido)propanoate (11.9 mg, 66% yield) as an oil. 1H NMR (400 MHz, CDCl3) δ: 8.48 (d, J=2.7 Hz, 1H), 7.88 (dd, J=8.3, 1.3 Hz, 1H), 7.74-7.67 (m, 2H), 7.46-7.41 (m, 2H), 7.41-7.29 (m, 3H), 6.81 (t, J=6.1 Hz, 1H), 6.69 (d, J=2.7 Hz, 1H), 4.42 (br. s., 1H), 4.25 (dd, J=9.3, 4.4 Hz, 1H), 4.19-4.08 (m, 2H), 3.70 (q, J=6.0 Hz, 2H), 2.61 (t, J=5.7 Hz, 2H), 2.59-2.45 (m, 1H), 2.07-1.97 (m, 1H), 1.76-1.67 (m, 2H), 1.66-1.55 (m, 1H), 1.28-1.21 (m, 3H), 1.13 (s, 3H), 1.09 (m, 3H). MS (M+1): 460.4.
