Reaction Steps

[(R)-4-(6-amino-3-fluoro-pyridin-2-yl)-5,5-difluoro-4-methyl-5,6-dihydro-4H-[1,3]oxazin-2-yl]-[bis-(4-methoxy-phenyl)-phenyl-methyl]-amine (250 mg, 0.444 mmol), 3-chloro-5-(trifluoromethyl)-picolinic acid (120 mg, 0.533 mmol) and HOAt (109 mg, 0.800 mmol) were dissolved in DMF (4.44 ml) under argon. EDC×HCl (128 mg, 0.667 mmol) was added and the reaction mixture was stirred at it for 18 hours. The reaction mixture was diluted with ethyl acetate, washed with water and brine, dried over sodium sulfate, filtered and concentrated. The crude product was chromatographed over silica gel (Redisep column 12 g, cyclohexane/ethyl acetate) to give the title compound: 100 mg (29.2% yield).
