実験手順

To a solution of (Z)-(1,2,3,4-tetrahydro-7-methoxy-1-naphthylidene)acetonitrile produced in Reference Example 2 (1.84 g, 9.23 mmol) in ethanol (10 ml) were added a saturated ammonia/ethanol solution (5 ml) and Raney cobalt (ODHT-60, 1.8 g). The mixture was stirred for 3 hours at room temperature under hydrogen atmosphere (about 4 kgf/cm2). The Raney cobalt was filtered off, then the solvent was distilled off to give the above-titled compound (a mixture of isomers) (yield 1.46 g, 78%, oil). This compound was used in the subsequent reaction without further purification.

後処理
