Reaktionsschritte

A round bottom flasked flushed with argon was charged with methyl 3-bromophenyl-acetate (2.29 g, 10 mmol) (prepared from 3-bromophenylacetic acid as described in example 2, step 1), morpholine (1.05 mL, 1.2 eq.), CsCO3 (4.55 g, 1.4 eq.), Pd2(dba)3 (92 mg, 0.01 eq) and BINAP (93 mg, 0.15 eq.) in toluene (20 mL). The resulting mixture was heated at 100° C. overnight and then diluted with diethyl ether (120 mL). The precipitates were filtered through a Celite pad and the filtrate was concentrated and purified on a silica-gel column with 20% EtOAc in hexane to give methyl 3-(morpholin-4-yl)phenylacetate (0.55 g, 23%).
