Reaction Steps

A mixture of (2-Chloro-3-pyridyl)-[2-methyl-6-(trifluoromethyl)spiro[3,4-dihydropyrrolo[1,2-a]pyrazine-1,4′-piperidine]-1′-yl]methanone (0.1 mol) and pyrrolidin-3-ol (0.3 mmol) DMF (0.5 mL) was stirred at 80° C. for 16 h. Additional pyrrolidin-3-ol (0.5 mmol) was added and the mixture was stirred at 150° C. for 16 h. The mixture was filtered and was subjected to preparatory-HPLC (10-90% ACN in water) to give (2-(3-hydroxypyrrolidin-1-yl)pyridin-3-yl)(2′-methyl-6′-(trifluoromethyl)-3′,4′-dihydro-2′H-spiro[piperidine-4,1′-pyrrolo[1,2-a]pyrazine]-1-yl)methanone. ESI-MS m/z calc. 463.5, found 464.3 (M+1)+; Retention time: 0.75 minutes (3 min run).
