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 C9H18Br (MH+-H2O): 205.0592, found: 205.0563.
