Reaction Steps

A mixture of 3-chloro-2-fluoro-6-methoxy-5-(1-{[9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl]amino}ethyl)benzaldehyde (10 mg, 0.023 mmol), in THF (0.95 mL) was stirred at 40° C. for 1 hour. Sodium triacetoxyborohydride (15 mg, 0.069 mmol) and acetic acid (50 μL, 0.88 mmol) were added and the mixture was stirred at 40° C. overnight. Morpholine (20 μL, 0.23 mmol) and sodium cyanoborohydride (14 mg, 0.23 mmol) were added and the mixture was heated at 40° C. for 1 hour. The solvents were stripped down and few drops of trifluoroacetic acid/THF solution (1:1) were added and the mixture stirred for 30 minutes. The mixture was treated with 6.0 M HCl in water (0.5 mL, 3 mmol) for 30 minutes. Purification by preparative LCMS (pH 10) gave the desired compound (3.4 mg, 35%). LCMS calculated for C19H23ClFN6O2 (M+H)+: m/z=421.2. found: 421.1. 1H NMR (DMSO-d6, 500 MHz) δ 12.91 (1H, br s), 8.17 (2H, m), 7.72 (1H, m), 5.89 (1H, br s), 4.05 (3H, s), 3.50 (7H, m), 2.41 (4H, m), 1.42 (3H, m).
