Reaction Steps
To a microtube with Pd(dppf)Cl2 (5.5 mg, 0.075 mmol) was added 2-methoxypyridin-3-ylboronic acid (0.10 mmol) in NMP (0.2 mL), followed by a solution of 1-(1-(4-bromo-3-methylbenzoyl)-2′-methyl-3′,4′-dihydro-2′H-spiro[piperidine-4,1′-pyrrolo[1,2-a]pyrazine]-6′-yl)-2,2,2-trifluoroethanone (0.75 mmol) in DMF (0.3 mL) and aq. Na2CO3 (2M, 4 mmol). The reaction mixture was shaken at 80° C. for 16 h. Filtration followed by purification using preparatory-HPLC (1-99% ACN in water (HCl modifier)) gave 2,2,2-trifluoro-1-[1′-[4-(2-methoxy-3-pyridyl)-3-methyl-benzoyl]-2-methyl-spiro[3,4-dihydropyrrolo[1,2-a]pyrazine-1,4′-piperidine]-6-yl]ethanone. ESI-MS m/z calc. 526.2, found 527.3 (M+1)+; Retention time: 1.38 minutes (3 min run).
