Procedure

Step 1C [Intermediate 3: 2-(4′-Hydroxymethyl-biphenyl4-sulfonylamino)-3-methyl-butyric acid methyl ester (1.2 g, 3.2 mmol, 1.0 equiv.), 2-chloro-3-methyl quinoline (2.26 g, 12.7 mmol, 4 equiv.) were dissolved in DMF (30 mL) followed by the addition of NaH (382 mg, 60% in oil, 9.54 mmol, 3 equiv.). The mixture was stirred at 100° C. for 5 hrs, then at room temperature overnight. The reaction mixture was then poured into cold water, solid precipitated from the mixture was collected by filtration and washed with water. Regular column chromatography (Silica gel, 1% MeOH/CH2Cl2) to yield 203 mg of 3-Methyl-2-[4′-(3-methyl-quinolin-2-yloxymethyl)-biphenyl-4-sulfonylamino]-butyric acid methyl ester in 12% yield.
