실험 절차
To -(6-fluoropyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)piperidin-2-one (290 mg, 0.894 mmol) in a steel bomb, ammonium hydroxide (34.8 μl, 0.894 mmol) solution was added (40% head volume remained). The steel bomb reactor was heated at 150° C. for 44 h (250 psi on pressure gauge). LCMS—0.23 min, MH+192.1 (without SEM); 0.66 min, MH+322.1 (with SEM). After diluted with MeOH and toluene, volatile materials were completely removed in vacuo. 5-(6-aminopyridin-3-yl)piperidin-2-one was used for the next step.
