Participants

Reaction Steps

A mixture of (2S,5R)-4-[6-(4-cyano-3-fluorophenyl)-2-(methylamino)-4-pyrimidinyl]-5-methyl-2-morpholinecarboxylic acid (300 mg, 0.81 mmol), HATU (340 mg, 0.89 mmol), and Hünig's base (0.21 mL, 1.20 mmol) in DMF (5 mL) was stirred at room temperature for 10 minutes. Aniline (0.085 mL, 0.93 mmol) was then added, and stirring continued at room temperature for 17 hours. LC-MS indicated about 50% conversion, so another portion each of Hünig's base (0.21 mL, 1.20 mmol) and HATU (340 mg, 0.89 mmol) were added. After about 10 minutes more aniline (0.085 mL, 0.93 mmol) was added, and the mixture was stirred for an additional 1.5 hours. It was then diluted with EtOAc (25 mL) and washed successively with water, saturated aqueous NaHCO3, and brine (25 mL each). The organic phase was then dried (Na2SO4), filtered, and concentrated in vacuo. The residue was purified by flash chromatography (40 g SiO2, 10-35% EtOAc in hexanes gradient) to give the title compound (340 mg, about 80% purity) as a yellow oil. LC-MS (ES) m/z=447 [M+H]+.
