Versuchsvorschrift

A solution of (R)-tert-butyl 5-chloro-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (30 mg, 0.066 mmol) in DCM was treated with 4N HCl in dioxane (0.5 mL). The reaction was stirred at about room temperature overnight. The reaction was concentrated and triturated with ether (×2) to yield (R)-5-chloro-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]dihydrochloride (21 mg, 73%). LCMS (APCI+) m/z 355, 357 [M+H]+; Rt=2.09 min.
