実験手順

To a solution of (S)-2-(4-(3-amino-6-((1R,3R,4R)-3-fluoro-4-hydroxycyclohexyl)pyrazin-2-yl)-2-fluorobenzamido)-2-(3-fluoro-5-iodophenyl)ethyl di-tert-butyl phosphate (315 mg, 0.392 mmol) was added HCl 4M in dioxane (5 mL, 20.00 mmol) and methanol (Volume: 0.5 mL). The reaction mixture was stirred at room temperature for 1 hour followed by LCMS. The solvent was concentrated off. The crude material was basified and dissolved with 3M NaOH solution with minimal MeOH added. The material was purified by 12 gram Grace Reveleris C18 reverse phase column eluted with 0-15% ACN/water over 18 minutes at a flow rate of 15 ml/minute, without buffers. The desired fractions were collected, acidified with 1 M HCl to pH of 1 and extracted with ethyl acetate (5×). The combined organic layer (800 ml) was washed with minimal water (3×25 ml) to remove salts. The solvent was concentrated off, dissolved in 1:1 ACN/water and lyophilized to give 207 mg of the desired product as HCL salt. (72% yield). LCMS (m/z): 693.2 (MH+), 0.64 min. 1H NMR (<cd3od>) d: 7.87 (s, 1H), 7.81-7.86 (m, 1H), 7.65-7.72 (m, 2H), 7.61 (dd, J=11.7, 1.6 Hz, 1H), 7.46 (ddd, J=8.0, 2.3, 1.4 Hz, 1H), 7.26 (dt, J=9.5, 1.9 Hz, 1H), 5.38 (t, J=5.7 Hz, 1H), 4.29-4.49 (m, 1H), 4.18-4.29 (m, 2H), 3.64 (tdd, J=11.6, 8.6, 4.9 Hz, 1H), 2.76-2.92 (m, 1H), 2.27 (ddd, J=8.8, 5.9, 2.5 Hz, 1H), 2.01-2.13 (m, 1H), 1.76-1.94 (m, 2H), 1.58-1.71 (m, 1H), 1.39-1.55 (m, 1H). 31P NMR (<cd3od>) d: 0.16 (br. s., 1P).
