Reaktionsschritte

The oil comprising 2-Phenoxyethyl methanesulfonate was prepared as described above in Example 1. The acylation and workup procedure was identical to that of Example 1 with the exception that 30.26 g (220 mmol) 2-phenylacetic acid was reacted instead of the 2-phenylbutyric acid. The organic layer obtained by the workup procedure was cooled to 25° C. and stirred at this temperature for 1 hour. The resulting crystallized product was filtered, washed with toluene and dried under vacuum at 40° C. to yield 53.18 g (159 mmol) of the 4-(2-mesyloxyethoxy)phenyl benzylketone as a tan colored solid. Yield: 80% on 2-phenoxyethanol.
