Procedure

Added trifluoroacetic acid (1 ml, 12.98 mmol) to a solution of (R)-tert-butyl 4-(5-(4-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)carbamoyl)-1-isopropyl-3-methyl-1H-indol-6-yl)pyridin-2-yl)-3-methylpiperazine-1-carboxylate (57 mg, 0.091 mmol) in DCM (3 mL) and let stir at RT for 1 hour. Concentrated on rotovap. Partitioned between DCM and sat'd Na2CO3, separated and washed DCM phase with water, brine, dried (MgSO4), filtered and rotovapped off DCM. Obtained 25 mg of the title compound as a tan solid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.19 (d, 2 H), 1.46-1.59 (m, 6 H), 2.21 (s, 3 H), 2.27 (s, 3 H), 2.44 (s, 3 H), 2.83 (dd, J=12.13, 3.54 Hz, 1 H), 2.96-3.29 (m, 4 H), 3.90 (br. s., 1 H), 4.47-4.76 (m, 5 H), 6.00 (s, 1 H), 6.51 (d, J=8.59 Hz, 1 H), 7.05 (s, 1 H), 7.45 (s, 1 H), 7.68 (dd, J=8.72, 2.40 Hz, 1 H), 8.43 (d, J=2.27 Hz, 1 H), 10.11-12.70 (m, 1 H). LCMS: [M+H]+ 527.5.
