A solution of (3R,4R)-4-[(R)-7-(2,6-difluoro-phenyl)-4-methyl-3-oxo-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-yl]-3-methyl-piperidine-1-carboxylic acid tert-butyl ester (0.005 g, 0.01 mmol) in HCl (4M in EtOAc, 1 mL) was stirred at ambient temperature for 1 h. The solvent was removed in vacuo to give crude (R)-7-(2,6-difluoro-phenyl)-4-methyl-6-((3R,4R)-3-methyl-piperidin-4-yl)-2,10-dihydro-9-oxa-1,2,4a-triaza-phenanthren-3-one hydrochloride (0.005 g, 100%), which was used directly in the next step without purification. LC/MS (Table 1, Method 25) Rt=0.717 min.; MS m/z: 427 [M+H]+.
