62% | With sodium tetrahydroborate; cobalt(II) chloride In methanol at 0 - 20℃; for 1.33333h; Inert atmosphere; | 77 (4-Bromo-2-methoxy-phenyl)methanamine General procedure: Following general procedure Q, 4-bromo-2-methoxybenzonitrile (108 mg, 0.51 mmol) gave (4-bromo- 2-methoxy-phenyl)methanamine (67.2 mg, 0.31 mmol, 61 % yield). NMR (500 MHz, CDCI3, δ): 7.12-7.02 (m, 2H), 7.00-6.96 (m, 1 H), 3.84 (s, 3H), 3.77 (s, 2H). To a solution of cobalt (II) chloride (1 eq.) and nitrile derivative (1 eq.) in anhydrous MeOH (0.05 M), cooled to 0 °C under a nitrogen atmosphere, was added sodium borohydride (10 eq) portion wise over 10 min. The reaction mixture was then stirred for 20 min at 0 °C and then stirred for a further 60 min at room temperature, quenched with an aqueous solution of ammonium chloride, and allowed to stand overnight. Most of methanol was removed under reduced pressure and the remaining aqueous mixture was diluted with water and washed with Ε2θ (x 2). The aqueous layer was basified to pH = 12 with 1 M NaOH and extracted with CHC (* 3). The combined organics were dried (phase separator) and concentrated to give the desired amine. |

With triethylamine In dichloromethane at 0 - 20℃; for 0.0833333h; | P9 tert-Butyl (4-bromo-3-methoxybenzyl Carbamate (P9) A solution of Boc20 (1.70 g, 7.80 mmol) in CH2C2(10 mL) was added to a suspension of (4- bromo-3-methoxyphenyl)methanamine (1.70 g, 7.80 mmol) and Et3N (1 .60 g, 15.6 mmol) in CH2CI2(20 mL) for 5 min at 0°C under a CaCl2tube. The mixture was stirred overnight at rt, diluted with H2O (500 mL) and the organic layer was separated. The aq. layer was extracted with CHCI3(3 x 50 mL). The combined organic layer was washed with H2O (50 mL) and brine (50 mL), dried over Na2SO4, filtered, concentrated and purified by FCC (PE:EA = 10:1 ) to give compound P9 as a white solid. |
