Reaction Conditions

Reaction Steps

To a solution of α-bromophenylacetic acid methyl ester, 5.0 g (22.0 mmol) in 120 mL of tetrahydrofuran was added 12 mL (88.0 mmol) of triethylamine and 5.4 g (66.0 mmol) of dimethylamine hydrochloride. The reaction mixture was heated at 60° C. in a sealed tube for three hours, cooled to ambient temperature and concentrated to dryness. The residue was partitioned between 20% isopropanol/chloroform and water. The mixture was washed with saturated sodium bicarbonate, washed with brine, dried over sodium sulfate, filtered and concentrated to dryness. The residue was purified by chromatography using a methanol/chloroform gradient as eluent and concentrated to dryness to yield 1.86 g (44%) of the desired isomer as a yellow oil. MS (ion spray) 193.9 (M+).
