Hydrochloric Acid → (1'-benzyl-1-(5-isopropyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4'-piperidine]-4-yl)methanamine trihydrochloride

Participants

Reaction Steps

A solution of tert-butyl (1′-benzyl-1-(5-isopropyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-4-yl)methylcarbamate (1.00 g, 1.76 mmol) in DCM (8 mL) was treated with 4N HCl in dioxane (2 mL). The reaction was stirred at room temperature for 1 hour and concentrated under reduced pressure to yield (1′-benzyl-1-(5-isopropyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-4-yl)methanamine trihydrochloride. LCMS (APCI+) m/z 468.2 [M+H]+; Rt=3.42 min.
