Reaction Steps

A mixture of 85 mg (0.17 mmol) of Cis(±)-ethyl 5-(aminocarbonyl)-2-(4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)isonicotinate (Example 198) and 86 mg (0.50 mmol) Ba(OH)2 in 3 ml MeOH and 2 ml water was heated at 120° C. for 1 h. The mixture was acidified to about pH=4 with 1N HCl and extracted 4 times with EtOAc. The EtOAc was concentrated and the residue was purified by reverse phase HPLC (20-40% CH3CN gradient in water with 0.1% TFA) to afford 8 mg of product as a white solid. MS (ES) MH+: 470 for C19H21Cl2N5O5; NMR: 1.5-1.8, (m, 3H), 2.2 (s, 3H), 3.0-3.2 (m, 2H), 3.3 (s, 3H), 3.5 (m, 2H), 4.2-4.5 (m, 2H), 4.9 (d, 1H), 6.9 (s, 1H), 7.1-7.3 (m, 2H), 7.8 (s, 1H), 8.4 (s, 1H), 12.1 (s, 1H), 13.1 (s, 1H).
