Reaction Steps

To a stirred solution of trans-[4-amino-2-(4-amino-cyclohexylamino)-pyrimidin-5-yl]-(2,3-difluoro-6-methoxy-phenyl)-methanone (105 mg, 0.28 mmol, Example 120) and sodium bicarbonate (84 mg, 1 mmol) in 1,4-dioxane (3 mL), bis-2-chloroethyl-methylamine hydrochloride (58 mg, 0.30 mmol, Aldrich) was added and the mixture was stirred at reflux overnight. An additional 20 mg of bis-2-chloroethyl-methylamine hydrochloride (Aldrich) was added and the reaction was refluxed for another 12 hours. The reaction was quenched with water and the mixture was extracted with ethyl acetate (3×10 mL) and the extracts were dried with sodium sulfate. Removal of solvent gave a yellow solid which was chromatographed (8% 9N ammonia in methanol/dichloromethane) to give a pale yellow solid. 16 mg, 12%. MS (ES) MH+=461.
