(S)-3-[6-(5-Chloro-6-methoxy-pyridin-3-yl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy]-pyrrolidine-1-carboxylic acid tert-butyl ester (766.2 mg, 1.66 mmol) was dissolved in a TFA/CH2Cl2 (1/2) solution and stirred at rt for 1 h. The reaction mixture was concentrated under vacuum, the residue was diluted with CH2Cl2, the organic layer washed with NaOH 1N then brine, dried over Na2SO4, filtered and evaporated to give 6-(5-chloro-6-methoxy-pyridin-3-yl)-4-((S)-pyrrolidin-3-yloxy)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidine. LCMS: [M+H]+=362.1, Rt(3)=1.28 min.
