Procedure

A solution of 174 mg (0.465 mmol) of 3-t-butoxycarbonylamino-3-methyl-N-[2,3,4,5-tetrahydro-2oxo-1H-1-benzazepin-3(R)-yl]-butanamide (Example 1, Step I) in 3.0 mL of dry dimethylformamide was treated with 22.2 mg of 60% sodium hydride oil dispersion (13.3 mg NaH, 0.558 mmol, 1.2 eq). The reaction mixture was stirred at room temperature for 30 minutes. To the solution was added 153 mg (0.465 mmol) of a solution of 4-bromomethyl-2'-(2-thienyl)-1,1'-biphenyl dissolved in 3 mL of dry dimethylformamide. After stirring at room temperature for 3 hours, the reaction mixture was diluted with ethyl acetate. The organic layer was washed with water (4×), dried over magnesium sulfate, filtered and evaporated under vacuum. The residue was purified by chromatography on silica gel, eluting with hexane/ethyl acetate (1:1) to give 160 mg of the product.
