実験手順

To 4-(3-amino-6-(4-((tert-butoxycarbonyl)amino)cyclohexyl)pyrazin-2-yl)-2-fluorobenzoic acid (222 mg, 0.516 mmol) was added DMSO (4 mL), Hünig's base (0.450 mL, 2.58 mmol), (S)-2-amino-2-(3-chlorophenyl)ethanol (133 mg, 0.774 mmol) and then HATU (392 mg, 1.031 mmol). The reaction was stirred for 1 h at room temperature. To the reaction was added 50 mL of ethyl acetate, washed with water twice, saturated salt solution, dried over sodium sulfate, filtered and concentrated to residue. The crude was purified by flash chromatography using 12 gram column (solid load) eluting with 10-95% ethyl acetate in heptane. The desired fractions were concentrated to constant mass to give 252 mg of product (which is 2:1 trans to cis ratio), used as is (83% over two steps). LCMS (m/z): 584.3 (MH+), 0.91 min for both.
