Reaction Steps

To a solution of HCl (30.0 equiv.) in dioxane was added to tert-butyl (1R,2S,3S,5R)-5-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-3-methyl-2-(methylthio)cyclohexylcarbamate (1.0 equiv.). The solution was capped and left standing at rt for 1 hr. The volatiles were removed in vacuo, dissolved in DMSO and purified by reverse phase HPLC to yield N-(4-((1R,3R,4S,5S)-3-amino-5-methyl-4-(methylthio)cyclohexyl)pyridin-3-yl)-6-(2,6-difluorophenyl)-5-fluoropicolinamide in 94% yield. LC/MS (m/z)=487.2 (MH+), Rt=0.65 min. 1H NMR (400 MHz, <dmso>) δ ppm 10.44 (s, 1H), 8.58 (d, J=4.0, 1H), 8.47 (d, J=4.0, 1H), 8.34 (dd, J=8.0, 4.0, 1H), 8.20 (dd, J=8.0, 8.0, 1H), 8.20 (dd, J=16.0, 4.0, 1H), 7.67-7.74 (m, 1H), 7.36 (dd, J=8.0, 8.0, 2H), 7.26 (d, J=4.0, 1H), 2.85-2.95 (m, 2H), 2.18 (s, 3H), 1.88-1.98 (m, 1H), 1.74-1.84 (m, 1H), 1.48-1.56 (m, 1H), 1.38-1.48 (m, 1H), 1.18-1.28 (m, 1H), 1.02 (d, J=8.0, 3H).
