Procedure
N,N′-Carbonyldiimidazole (131 mg, 0.813 mmol) was added to a solution of (S)-2-((2-(4-methoxy-2,6-dimethylphenylsulfonyl)-1,2,3,4-tetrahydroisoquinolin-3-yl)methoxy)-acetic acid (step d, Example 127) (325 mg, 0.775 mmol) in dichloromethane (5 ml), and stirring was carried out for 2 h at 30° C. A solution of 1-((1-methylpiperidin-4-yl)methyl)piperazine (152 mg, 0.775 mmol) in dichloromethane (5 ml) was then added at room temperature, and the reaction mixture was stirred for 15 h at that temperature. Saturated sodium hydrogen carbonate solution (10 ml) was added to the mixture, and the aqueous phase was extracted with dichloromethane (20 ml). The combined organic phases were dried (Na2SO4) and concentrated in vacuo. The crude product was purified by column chromatography (silica gel) using ethyl acetate/methanol/ammonia solution (25% aq.) (40:10:0.5). Yield: 263 mg (57%); MS, m/z 599.3 (MW).
