Reaction Conditions

Reaction Steps

3-(4-Bromophenyl)propan-1-ol (335 g) and dichloromethane (2.5 L) was charged into Reactor 1. Reactor 1 was adjusted to −10 to 0° C. Triethylamine (205 g) was charged into Reactor 1. Methanesulphonyl chloride (272.7 g) was added dropwise into Reactor 1 maintaining contents at <0° C. Reactor 1 was stirred at −5 to 5° C. for 1 h then analysed for reaction completion. The organic layer was washed with water (1 L) and saturated NaCl solution (1 L). The organic layer was evaporated down to dryness to give 3-(4-bromophenyl)propyl methanesulfonate (418 g).
