Reaction Steps

Step 2 {(R)-1-[4-Chloro-3-(6-chloro-pyridine-3-carbonyl)-2-fluoro-phenyl]-propyl}-carbamic acid tert-butyl ester (6.4 g, 15 mmol) was suspended in 7M NH3 in MeOH (32 mL) and split over 4 Reacti-vials and all heated at 100 degC overnight. The mixture was then evaporated down and purified by silica column, eluting 20-100% EtOAc in petroleum ether to give {(R)-1-[3-(6-amino-pyridine-3-carbonyl)-4-chloro-2-fluoro-phenyl]-propyl}-carbamic acid tert-butyl ester (3.1 g, 7.6 mmol, 51%). [MH]+ 408
