Procedure

Methyl 6-(4-((S)-1-((S)-6-(2-hydroxy-2-methylpropyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)phenyl)nicotinate (150 mg, 0.307 mmol) was dissolved in NH2Me/MeOH (10 mL). The mixture was stirred at rt overnight. The solvent was removed in vacuo to give the crude product, which was purified by preparative HPLC and chiral HPLC to afford 6-(4-((S)-1-((S)-6-(2-hydroxy-2-methylpropyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)phenyl)-N-methylnicotinamide (54 mg, 36%).
