Procedure

To a solution of (R)-4-(phenylthio)-3-(4-sulfamoyl-2-(trifluoromethylsulfonyl)phenylamino) butanoic acid (INTERMEDIATE 8, 500 mg, 1.00 mmol), (S)—N-ethyl-N-(morpholin-3-ylmethyl)ethanamine hydrochloride salt (INTERMEDIATE 86, 50 mg, 1.2 mmol), DIPEA (0.526 ml, 3.01 mmol), in DMA (5 ml) was added HATU (458 mg, 1.20 mmol). The mixture was stirred for 1 hour at room temperature and diluted with ethyl acetate (200 ml). The mixture was washed successively with 1 M aq. sodium bisulfate, saturated sodium bicarbonate, and brine. The organic phase was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The concentrate was purified column chromatography (ISCO, eluting with 0→100% DCM/10% 2 M ammonia in MeOH in DCM over 24 minutes) to give the title product (380 mg, yield: 58%).
