실험 절차

To a solution of 2-(2-tosyl-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-1-yl)acetic acid (S11) (300 mg, 0.898 mmol, 1.0 eq.) in THF (5 ml) were added DIPEA (0.47 ml, 2.694 mmol, 3.0 eq.) and HATU (410 mg, 1.08 mmol, 1.2 eq.) at 0° C. and the mixture was stirred for 15 min at the same temperature. A solution of (R)-6-((tert-butylamino)methyl)-1,2,3,4-tetrahydronaphthalen-1-amine (A50) (0.898 mmol, 1.0 eq.) in THF (5 ml) was added to the reaction mixture and it was stirred at RT for 16 h. The reaction mixture was diluted with ethyl acetate (50 ml) and washed with sat. NH4Cl solution (20 ml), sat. NaHCO3 solution (20 ml), water (20 ml) and brine (20 ml). The organic layer was dried over Na2SO4 and concentrated under reduced pressure to get the crude product which was purified by column chromatography (silica gel; 1.5% MeOH/DCM) to yield the desired product as an off-white solid. Yield: 19% (94 mg, 0.171 mmol); MS, Rt=3.2 min; m/z=549.1 [MH]+
