Methanol → Methyl 6-Bromohexanoate

To a 1 L round bottom flask, charged with 20 g (102.5 mmol) of 6-bromohexanoic acid and 500 mL of methanol was bubbled hydrogen chloride gas for 2-3 minutes. The mixture was stirred at room temperature for 4 h and then concentrated to afford 21.0 g of the product (1) as a yellow oil (99%): 1H-NMR (200 MHz, d6-DMSO); 3.57 (s, 3H), 3.51 (t, 2H), 2.30 (t, 2H); 1.78 (pentet, 2H), and 1.62-1.27 (M, 4H) ppm.
