Reaction Steps

Into a microwave vial was added tert-butyl 4-{3-chloro-2-fluoro-6-methoxy-5-[1-(9H-purin-6-ylamino)ethyl]phenyl}-3,6-dihydropyridine-1(2H)-carboxylate (10.5 mg, 0.021 mmol) and 4.0 M HCl in 1,4-dioxane (1.0 mL). The mixture was stirred for 30 min and evaporated. Methylene chloride (1.0 mL) and DIPEA (15.6 μL, 0.090 mmol) were added followed by methanesulfonyl chloride (4.8 pt, 0.063 mmol). The mixture was stirred for 15 minutes. The solvents were evaporated. 1 N sodium hydroxide solution (1.0 mL) and methanol (1.0 mL) were added and the mixture was stirred for 1 hour. The solvents were evaporated and purification by preparative LC/MS (pH 10) gave the desired compound (4.0 mg, 40%). LCMS calculated for C20H23ClFN6O3S (M+H)+: m/z=481.1. found: 481.0. 1H NMR (DMSO-d6, 500 MHz) δ 12.88 (1H, br s), 8.18 (2H, m), 7.63 (1H, m), 5.91 (1H, m), 5.78 (1H, br s), 3.94 (5H, m), 3.40 (2H, m), 2.98 (3H, s), 2.55 (2H, m), 2.39 (2H, m), 1.42 (3H, m).
