a-(1 H-tetrazol-5-yl)-3-fluoro-4-phenylethylbenzene (4)With the Same procedure from4 g (0.0177 mole) of 8,2.8 g (60 % yield) of 4, m.p.The isomerization of trans-2-acetamido-3-hydroxy-5,8-dimethoxytetraline (1) under the action of hydrogen chloride was investigated. Hydrolysis of 5,8-dimethoxy-2-methyI-3a,4,9,9u-tetrahydronaphth[2,3-d]oxazoline hydrochloride (2) leads to cis-2-amino-3-hydroxy-5,8-dimethoxytetraline (3). 0365-6233/83/0909M55 $ 02.50/0 r 1 H L J l a
