実験手順
Starting with cis-1-(3,4-dimethoxybenzoyl)-2-methyl-1,2,3,4-tetrahydro-4-quinolinol (1.00 g, 2.93 mmol) prepared in Reference Example 1 and 3,4-dihydro-2H-1,4-benzothiazine (1.22 g, 8.07 mmol), the same procedure as shown in Example 1 was repeated to give the titled compound (335 mg, yield: 25%) as a white crystal. (cis:trans=1.5:1)
