Mode opératoire

Step 5 (A): N1-((1S,2S)-1-((R)-4-benzhydrylmorpholin-3-yl)-3-(3,5-difluorophenyl)-1-hydroxypropan-2-yl)-N3,N3-dipropylisophthalamide. To a solution of 3-(dipropylcarbamoyl)benzoic acid (Preparation E, 14 mg, 0.055 mmol) in dichloromethane (1 mL) was added Hunig's base (18 mg, 0.14 mmol) to make a clear solution and HATU (25 mg, 0.064 mmol) was then added. After stirring for 20 min, the reaction mixture was added (1S,2S)-2-amino-1-((R)-4-benzhydrylmorpholin-3-yl)-3-(3,5-difluorophenyl)propan-1-ol (Preparation D, (20 mg, 0.046 mmol) and the reaction mixture was stirred at rt overnight. Dichloromethane (100 mL) was added and washed with H2O (50 mL) twice, dried over Na2SO4, and concentrated to give the title compound as a crude product ready for next step without purification: 1H NMR (CD3OD, 500 MHz) δ 0.71 (3H, m), 1.01 (3H, m), 1.52 (2H, m), 1.74 (2H, m), 2.52 (1H, d, J=5 Hz), 2.63 (2H, dd, J=5, 15 Hz), 2.71 (1H, m), 3.12-3.19 (3H, m), 3.44-3.49 (3H, m), 3.94-3.99 (2H, m),4.04 (1H, m), 4.58 (1H, m), 5.06 (1H, m), 5.50 (1H, s), 6.76 (1H, m), 6.92-6.95 (2H, m), 7.14-7.19 (3H, m), 7.25-7.32 (3H, m), 7.44 (2H, m), 7.49-7.55 (2H, m), 7.58 (2H, d, J=10 Hz), 7.63 (1H, s), 7.73-7.76 (1H, m).
