50% | A solution of 4 -BROMOBIPHENY-4-OL (883 mg, 3.55 mmol) in DMF (10 mL) was treated with NaH (148 mg, 3.72 mmol). After stirring for 10 min, (L)-4-bromo-2-tert-butoxycarbonylamino- butyric acid methyl ester (1 g, 3.38 mmol) was added and the reaction mixture was stirred an additional 16 h. Once complete, the reaction mixture was diluted with ethyl acetate (100 mL), washed successively with sat. aq NH4CL and sat. aq NaCl, dried over MGS04, filtered, and concentrated. Purification by flash column chromatography (10% ethyl acetate in heptane) provided 4- (4 -BROMOBIPHEN-4-YLOXY)-2-TERT- butoxycarbonylaminobutyric acid methyl ester as white solid (0.79 g, 50%). 1H NMR (CDC13), 8 7. 50 (d, J = 8 Hz, 2 H), 7.44 (d, J = 8 Hz, 2 H), 7.38 (d, J = 8 Hz, 2 H), 6.92 (d, J = 8 Hz, 2 H), 5.28 (m, 1 H), 4.51 (m, 1 H), 4. 08 (t, J = 8 Hz, 2 H), 3.77 (s, 3 H), 2.34 (m, 2 H), 1.44 (s, 9 H).
