実験手順

A mixture of 2-trifluoroacetyl-1,2,3,4-tetrahydro-isoquinoline-7-sulfonyl chloride (400 mg, 1.22 mmol, J. Med. Chem. 1980, 23, 837), dimethylamine hydrochloride (150 mg, 1.83 mmol), and triethylamine (0.50 mL, 3.66 mmol) in dioxane (10 mL) was refluxed with stirring for 30 min, cooled to room temperature, concentrated, and purified by flash column chromatography (10→50% ethyl acetate/hexanes) to give 337 mg (82%) of the title compound of Example 247, Step A as a yellow oil. 1H NMR (CDCl3, 300 MHz, 9:5 mixture of rotamers) δ 7.67-7.52 (c, 2H), 7.36 (t, 1H), 4.87 (s, 1.3H), 4.81 (s, 0.7H), 3.96-3.86 (c, 2H), 3.08-3.02 (c, 2H), 2.72 (s, 6H); MS (TS) 337 (MH+).
