Reaction Steps

To a suspension/solution of ethyl 2-((3S,4R)-4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)-4-[(methylamino)carbonyl]-1,3-thiazole-5-carboxylate (0.078 g, 0.15 mmol, Example 218) in methanol (2 mL) was added barium hydroxide (0.052 g, 0.30 mmol) and water (0.5 mL). After stirring several hours the reaction was complete. The reaction was acidified with 1N HCl and then concentrated to remove methanol. The residue was extracted with EtOAc (×3), dried with MgSO4 and concentrated to a white solid (0.059 g). MS (ES) M+H+: 490 for C18H21Cl2N5O5S; NMR: 1.76 (s, 2 H) 2.18 (s, 3 H) 2.86 (s, 3 H) 3.38 (s, 3 H) 3.56 (s, 2 H) 4.02 (s, 1 H) 4.27 (s, 2 H) 4.40 (s, 1 H) 7.15 (s, 1 H) 9.38 (s, 1 H) 12.15 (s, 1 H).
