YieldReaction ConditionsOperation in experiment
69% In xylene; for 5h;Heating / reflux; Step 2. Preparation of tert-butyl (3R)-3-r(6-bromo-4-oxoauinazolin-3(4H)-vl)methvl1-piperidine-1 -carboxylate; [353] A mixture of 6-bromo-4H-3,1-benzoxazin-4-one (14.0 g, 61.94 mmol) (step 1) and tert-butyl (3R)-3-(aminomethyl)piperidine-1 -carboxylate (15.9 g, 74.33 mmol) was heated under refluxin xylene for 5 h. After cooling to rt, the organic solvent was removed under reduced pressure,and the crude material purified by silica gel column chromatography (elution with 40% EtOAc inhexane) to afford 18.2 g (69%) of the product as a yellow-brown oil. ES-MS m/z 322.2 ([MH2-BOC]+); HPLC RT (min) 3.34.
