Procedure

DIEA (0.11 mL, 0.654 mmol) was added to (S)—N1-(14-amino-3-methyl-6,9,12-trioxa-3-azatetradecyl)-N3-(4-(diethylamino)-2-(4-(1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl)pyridin-2-yl)phenyl)-N1-methylisophthalamide tetrahydrochloride 340a (0.101 g, 0.106 mmol), 4-acetoxybenzoic acid (19.1 mg, 0.106 mmol) and HATU (48 mg, 0.127 mmol) in DMF (2 mL) and the mixture stirred for 2 hours at room temperature. The reaction was diluted with ethyl acetate, washed with water and brine, dried (MgSO4) and evaporated. The residue was purified by PTLC (10% methanol/20% ethyl acetate/dichloromethane) to give the intermediate (S)-4-(1-(3-(4-(diethylamino)-2-(4-(1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl)pyridin-2-yl)phenylcarbamoyl)phenyl)-2,5-dimethyl-1-oxo-8,11,14-trioxa-2,5-diazahexadecan-16-ylcarbamoyl)phenyl acetate as a yellow foam (0.082 g, 75%); MS (ES, m/z): 972 [M+H]+. Ammonia in methanol (2M, 4 mL) was added and the mixture stirred overnight at room temperature. The reaction was evaporated and the residue purified by PTLC (10% methanol/20% ethyl acetate/dichloromethane) to give product as a yellow foam (0.065 g, 83%); MS (ES, m/z): 928 [M+H]+; NMR (400 MHz, DMSO-d6, ppm): δ 11.7 (m, 1H); 9.93 (s, 1H); 9.13 (d, J=8.4 Hz, 1H); 8.83 (d, J=5.2 Hz, 1H); 8.21 (m, 2H); 7.96-8.06 (m, 1H); 7.84-7.94 (m, 2H); 7.80 (d, J=4.8 Hz, 1H); 7.70 (dd, J=2.0 and 6.8 Hz, 2H); 7.60 (m, 2H); 7.09-7.19 (m, 4H); 7.06 (d, J=3.2 Hz, 1H); 6.85 (dd, J=2.8 and 8.8 Hz, 1H); 6.77 (m, 2H); 5.23 (m, 1H); 3.35-3.60 (m, 25H); 2.99 (m, 3H); 2.92 (m, 2H); 2.33 (m, 1H); 1.90-2.04 (m, 3H); 1.70-1.86 (m, 2H); 1.12 (t, J=6.8 Hz, 6H).
