4-dimethylphosphoryl-2-fluoroaniline

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 3,6-dichloro-N-[2-(propan-2-ylsulfonyl)phenyl]-1,2,4-triazin-5-amine (prepared as in Example 106: 0.7 mmol), 4-(Dimethylphosphoryl)-2-fluoroaniline (0.7 mmol) and camphorsulfonic acid (0.7 equiv.), is refluxed for 20-48 hours in 2-propanol. The reaction mixture is allowed to cool to room temperature, dissolved in dichloromethane and washed with an aqueous solution of Na2CO3. The dichloromethane extract is dried over MgSO4 and evaporated. The crude product is purified by Prep-HPLC. washed with an aqueous solution of Na2CO3 The dichloromethane extract is dried over MgSO4 evaporated The crude product is purified by Prep-HPLC

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 4-bromo-2-fluoroaniline (0.380 g, 2.00 mmol) in 8 mL DMF was added dimethylphosphine oxide (0.171 g, 2.20 mmol), palladium acetate (22.4 mg, 0.0100 mmol), XANTPHOS (69.4 mg, 0.120 mmol), and potassium phosphate (0.467 g, 2.20 mmol). The mixture was purged with nitrogen, and subjected to microwaves at 150° C. for 20 minutes. The reaction mixture was concentrated and purified by silica gel chromatography (0-20% 7N ammonia in methanol:dichloromethane) to afford the desired product (73.5 mg, 20% yield). The mixture was purged with nitrogen The reaction mixture was concentrated purified by silica gel chromatography (0-20% 7N ammonia in methanol:dichloromethane)

Procedure: To a solution of 2,5-dichloro-N-[2-(propan-2-ylsulfonyl)phenyl]pyrimidin-4-amine (as prepared in Example 17: 0.040 g, 0.12 mmol) in 1 mL of 2-methoxyethanol was added 4-(dimethylphosphoryl)-2-fluoroaniline (0.023 g, 0.12 mmol) and 49 μL of 2.5 M HCl in ethanol. The mixture was heated in a sealed tube at 90° C. for 16 h. The mixture was basified with 1N NaOH solution, and extracted with ethyl acetate. The organic layers were combined, washed with saturated sodium chloride solution, dried with sodium sulfate, filtered and concentrated. The crude residue was purified by prep-HPLC to afford the final compound (9.0 mg, 22% yield). MS/ES+: m/z=497. extracted with ethyl acetate washed with saturated sodium chloride solution dried with sodium sulfate filtered concentrated The crude residue was purified by prep-HPLC
