Reaction Steps

According to the procedure given for the synthesis of 206e, 205h (60.0 g, 183 mmol) was reduced with LiBH4 (5.96 g, 274 mmol) and methanol (8.55 g, 269 mmol) in anhydrous CH2Cl2 (390 mL). After the typical workup, crude 206h (51.0 g, 98%) was obtained as a yellowish oil, which was used without further purification for the next step. 1H NMR (CDCl3): δ 7.25-7.08 (m, 5 H), 3.64 (d, 1 H, J=7.2), 3.50 (d, 1 H, J=7.2), 3.35 (t, 2 H, J=6 Hz), 1.92-0.95 (m, 9 H), 1.28 (s, 3 H). 13C NMR (CDCl3): δ 144.77, 128.51, 126.76, 126.21, 72.63, 43.45, 38.37, 34.06, 32.73, 28.96, 23.12, 21.59. HRMS (EI): Calcd for C14H21BrO (M+); 284.0776, found: 284.0787.
