Reaction Steps

To (2R)-4-{4-[4-(4-methoxy-2H-1,2,3-triazol-2-yl)phenyl]-2-oxopyridin-1(2H)-yl}-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (120 mg, 0.22 mmol) was added dioxane (2 ml), dichloromethane (2 ml), and water (1 ml). The reaction flask was cooled externally with ice then treated with a 4.0M sol of HCl in dioxane (0.55 ml). The reaction mixture was stirred for 15 minutes then concentrated under reduced pressure. IPA (10 ml) was added and concentrated to azeotrope any remaining water to furnish a tan solid (80 mg, 80% TY). MS (LC/MS) m/z 462.3 (M+1). 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.74 (s, 3H) 2.34-2.51 (m, 1H) 2.55-2.81 (m, 1H) 3.13 (s, 3H) 3.96-4.06 (m, 1H) 4.07 (s, 3H) 4.26-4.45 (m, 1H) 6.84-7.00 (m, 2H) 7.49 (s, 1H) 7.75-7.93 (m, 3H) 8.09 (d, J=8.78 Hz, 2H)
