Procedure

Step 4 (A): N1-((1S,2S)-1-((2R,4R)-4-(allyloxy)-1-benzhydrylpyrrolidin-2-yl)-3-(3,5-difluorophenyl)-1-hydroxypropan-2-yl)-N3,N3-dipropylisophthalamide. To a solution of 3-(dipropylcarbamoyl)benzoic acid (31 mg, 0.12 mmol) in dichloromethane (3 mL) were added Hunig's base (43 mg, 0.33 mmol) and HATU (54 mg, 0.143 mmol). After stirring for 20 min, the reaction mixture was added (1S,2S)-1-((2R,4R)-4-(allyloxy)-1-benzhydrylpyrrolidin-2-yl)-2-amino-3-(3,5-difluorophenyl)propan-1-ol (Preparation (C), 54 mg, 0.11 mmol) and the reaction mixture was stirred at rt overnight. The crude mixture was purified by silica gel Flash Chromatography (0% to 20% to 40% to 50% EtOAc/Hexane step gradient) to give 70 mg of the title compound (89% yield): 1H NMR (CDCl3, 500 MHz) δ 0.74 (3H, brd s), 1.00 (3H, brd s), 1.53 (2H, brd s), 1.73 (2H, brd s), 2.02-2.09 (1H, m), 2.17 (1H, d, J=10 Hz), 2.26 (1H, dd, J=5, 10 Hz), 2.68 (1H, d, J=10 Hz), 2.84 (1H, dd, J=5, 15 Hz), 2.96 (1H, dd, J=5, 15 Hz), 3.09 (1H, d, J=10 Hz), 3.16 (2H, brd s), 3.25 (1H, d, J=10 Hz), 3.49 (2H, brd s), 3.91-3.93 (2H, m), 3.96-4.11 (3H, m), 4.50 (1H, s), 4.91 (1H, d, J=10 Hz), 5.22 (1H, dd, J=5, 10 Hz), 5.31 (1H, m), 5.90-5.98 (1H, m), 6.64-6.69 (3H, m), 6.91-6.97 (3H, m), 7.15-7.20 (3H, m), 7.22-7.25 (2H, m), 7.34 (2H, d, J=5 Hz), 7.47-7.57 (4H, m).
