Embodiment 10
[0178] Preparation of (RS)-S-[4-({5-bromo-4-[(R)-(2-hydroxy-1-methylethyl)amino]pyrimidin-2-yl}amino)phenyl]-S -Methylaminosulfoxide
[0179]
[0180] Method A
[0181] 40 mg (0.23 mmol) of (RS)-S-(4-aminophenyl)-S-methylaminosulfoxide and 62 mg (0.23 mmol) of (R)-2-[(5-bromo -2-chloropyrimidin-4-yl)amino]propan-1-ol with 0.5 ml of 1-butyl-3-methyl-imidazolium tetrafluoroborate (review article on ionic liquids: a) T.Welton, Chem.Rev.1999,99,2071; b) H.Zhao, Aldrichimica Acta2002,35,75; c) M.J.Earle, K.R.Seddon, ACS Symposium Series 2002,819,10) mixed, and at room temperature Stir for 10 minutes. The reaction mixture was heated to 60°C and stirred at this temperature for a further 3 hours. Mix with 0.08 ml of 4M hydrochloric acid solution in dioxane and stir at 60° C. for 60 hours. After cooling, the reaction mixture was mixed with 10 ml of ethyl acetate and stirred for 10 minutes. The organic solvent was decanted off, and the residue was dissolved in 10 ml methanol. ...

[0196] Preparation of (RS)-S-[3-({5-bromo-4-[(R)-(2-hydroxy-1-methylethyl)amino]pyrimidin-2-yl}amino)phenyl]-S -Methyl-N-nitroaminosulfoxide
[0197]
[0198] A solution of 37mg (0.17mmol) of (RS)-S-(3-aminophenyl)-S-methyl-N-nitroaminosulfoxide in 3ml of acetonitrile was mixed with 91mg (0.34mmol) of (R)- 2-[(5-Bromo-2-chloropyrimidin-4-yl)amino]propan-1-ol and 0.06 ml of 4M hydrochloric acid solution in dioxane were mixed and stirred overnight at reflux. A further 0.05 ml of 4M hydrochloric acid solution in dioxane was added and refluxed for a further 6 hours. After TLC monitoring, it was mixed with 92 mg (0.34 mmol) of (R)-2-[(5-bromo-2-chloropyrimidin-4-yl)amino]propan-1-ol and refluxed overnight. After cooling, the reaction was made basic with saturated sodium bicarbonate solution, then extracted with ethyl acetate. The combined organic phases were dried (Na 2 SO 4 ), filtered and concentrated by evaporation. The residue obtained is purified by chromatography (DC...
