Reaction Steps
According to the method for the synthesis of 206e, 205g (43.0 g, 0.16 mol) was treated with LiBH4 (5.55 g±0.25 mol) and methanol (7.75 g, 0.24 mol) in CH2Cl2 (200 mL) to give 206g (36.2 g, 98%) as a colorless, viscous oil. 1H NMR (CDCl3): δ 3.41 (t, 2H, J=6.9), 3.30 (br. s, 2H), 1.90-1.84 (m, 3H), 1.42-1.22 (m, 6H), 0.86 (s, 6H). 13C NMR (CDCl3): δ 71.9, 38.6, 35.1, 34.1, 32.9, 29.2, 24.0, 23.2. HRMS (LSIMS, nba): Calcd for C9H28Br (MH+−H2O): 205.0592, found: 205.0563.
