Conditions

Temperature
105 °C

Procedure

A mixture of dibutyl (4-aminobenzyl)phosphonate (18 mg, 0.06 mmol), N-[3-({[2-chloro-5-(trifluoromethyl)pyrimidin-4-yl]amino}methyl)pyridin-2-yl]-N-methylmethanesulfonamide XLIa (20 mg, 0.05 mmol), TFA (12 uL, 0.15 mmol) and TFE (0.5 mL) was heated at 105° C. under nitrogen in a microwave reactor for 40 minutes. The resulting mixture was concentrated in vacuo and the residue purified by preparative HPLC (MDP) to afford 24 mg of dibutyl [4-({4-[({2-[methyl(methylsulfonyl)amino]pyridin-3-yl}methyl)amino]-5-(trifluoromethyl)pyrimidin-2-yl}amino)benzyl]phosphonate trifluoroacetate (Example 26, yield 73%).
