実験手順

To a suspension of 2-(2-tosyl-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-1-yl)acetic acid (S11) (405 mg, 1.2 mmol, 1.0 eq.) in THF (5 ml) were added DIPEA (1.0 ml, 6.0 mmol, 5.0 eq.) and HATU (547 mg, 1.4 mmol, 1.2 eq.) at 0° C. and the mixture was stirred for 15 min at the same temperature. A solution of (R)—N-(4-(1-aminoethyl)-benzyl)-2-methylpropan-2-amine (A54) (1.2 mmol, 1.0 eq.) in THF (3 ml) was added to the reaction mixture and it was stirred at RT for 16 h. The mixture was diluted with DCM (70 ml) and washed with sat. NH4Cl solution (25 ml), sat. NaHCO3 solution (25 ml), water (25 ml) and brine (25 ml). The organic layer was dried over Na2SO4 and concentrated under reduced pressure to give the crude product which was purified by column chromatography (silica gel; 3% MeOH/DCM) to yield the desired product as a light brown solid. Yield: 29% (180 mg, 0.334 mmol); MS, Rt=2.9 min; m/z=523.1 [M H]+
