실험 절차

Pd(OH)2 (150 mg, 1.070 mmol) was put into a round flask and flushed under argon for 5 minutes. A solution of 1-[(S)-3-(6-benzyl-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy)-pyrrolidin-1-yl]-propan-1-one (560 mg, 1.528 mmol) in 22 mL of MeOH was added followed by ammonium formate (482 mg, 7.64 mmol). The reaction mixture was stirred under reflux (70° C.) for 2 h. The mixture was filtered over a pad of celite and dried under high vacuum to give 1-[(S)-3-(5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy)-pyrrolidin-1-yl]-propan-1-one. No further purification (m=420 mg, quantitative yield). MS: [M+H]+=277.5 Rt(6)=0.71 min.
