실험 절차

The crude (S)-4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-N-(2-azido-1-(3-fluoro-5-iodophenyl)ethyl)-2-fluorobenzamide was dissolved in THF (5 mL), and triphenylphosphine (polymer bound, 3 mmol/g) (0.97 g, 3.70 mmol) was added dropwise. The mixture was heated at 70° C. for 3 h. LCMS indicated absence of starting material (at this stage, the phosphorylimine intermediate is likely present in solid phase). Water (4.5 mL) and THF (5 mL) were added, and the mixture was heated at 80° C. for 3 h and then filtered. The filter cake was washed with DCM and then filtrate was concentrated in vacuo. The residue was dissolved in DCM and washed with water and the organic layer dried over magnesium sulfate, filtered and concentrated in vacuo to afford the residue which was purified by flash chromatography (0-60% DCM/10% MeOH in EtOAc containing 0.5% NH4OH), and the product fractions were collected and concentrated. The residue was dissolved in acetonitrile and water, and lyophillized to obtain 101.2 mg of (S)—N-(2-amino-1-(3-fluoro-5-iodophenyl)ethyl)-4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-2-fluorobenzamide as the desired product. LCMS (m/z): 580.1 (MH+), 0.70 min. 1H NMR (CD3OD) δ (ppm): 7.92 (s, 1H), 7.85-7.79 (m, 1H), 7.73 (dd, J=8.0, 1.4 Hz, 1H), 7.68-7.61 (m, 2H), 7.50-7.43 (m, 1H), 7.23 (d, J=9.5 Hz, 1H), 5.12 (t, J=6.9 Hz, 1H), 4.07 (dd, J=11.2, 3.3 Hz, 2H), 3.60 (td, J=11.7, 2.0 Hz, 2H), 3.09-2.83 (m, 3H), 2.02-1.76 (m, 4H).
