実験手順

(R)-4-(4-((tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)benzoic acid (INTERMEDIATE 13, 160 mg, 0.3 mmol), (R)-4-(4-((2-(tert-butyldiphenylsilyloxy)ethyl)(ethyl)amino)-1-(phenylthio)butan-2-yl amino)-3-(trifluoromethylsulfonyl)benzenesulfonamide (INTERMEDIATE 25, 216 mg, 0.27 mmol), DMAP (100 mg, 0.82 mmol), and EDC (104 mg, 0.54 mmol) were placed in a 50 ml flask and flushed with nitrogen. DCM (3 ml) was added, and the solution was stirred at room temperature overnight. The reaction mixture was diluted with DCM (40 ml) and washed with 1N aq. sodium bisulfate (35 ml) followed by a saturated aq. sodium bicarbonate (40 ml). The organic layer was dried (Na2SO4), filtered, and evaporated under reduced pressure to give a residue, which was purified by column chromatography (ISCO, 40 g silica gel column, eluting with 0→25% EtOAc/hexanes) to give 4-(4-((R)-(tert-butyldimethylsilyloxy)(4′-chlorobiphenyl-2-yl)methyl)piperidin-1-yl)-N-(4-((R)-4-((2-(tert-butyldiphenylsilyloxy)ethyl)(ethyl)amino)-1-(phenylthio)butan-2-ylamino)-3-(trifluoromethylsulfonyl)phenylsulfonyl)benzamide (EXAMPLE 4A, STEP 1, 140 mg), that was used in the preparation of EXAMPLE 4A, STEP 2, without further purification.
