실험 절차
Preparation 12a: (S)-tert-butyl 2-(5-(1-Methylpyrrolidin-2-yl)pyridin-3-yloxy)ethylcarbamate (preparation 11) (105 mg, 0.33 mmol) was stirred in trifluoroacetic acid (1 mL) and DCM (5 mL) for 1.5 h. The reaction mixture was evaporated, then co-evaporated with DCM (×5) and 20% ammonia in MeOH. The crude product was purified by flash chromatography (5% [20% ammonia in MeOH] in DCM) to give the title compound as a yellow oil (62 mg, 85%).
