PROCEDURE

实验过程

According to the procedure given for the synthesis of 206e, 205b (23.70 g, 79.21 mmol) was reduced with LiBH4 (3.45 g, 158.4 mmol) and methanol (5.24 g, 163.5 mmol) in anhydrous CH2Cl2 (150 mL) to give 206b (20.0 g, 98%) as an oil. 1H NMR (CDCl3): δ 7.34-7.14 (m, 5 H), 3.60 (m, 1 H), 3.48 (m, 1 H), 3.29 (t, 2 H, J=6.0), 1.96-1.44 (m, 5 H), 1.32 (s, 3 H). 13C NMR (CDCl3): δ 144.25, 128.59, 126.71, 126.41, 72.44, 43.15, 37.06, 34.64, 27.58, 21.61. HRMS (LSIMS, nba): Calcd for C12H16Br (MH+-H2O): 239.0435, found: 239.0444.
