At 0° C., 2M 2-methyl-2-butene in THF (15 mL, 30 mmol) was added to BH3.DMS (1.5 mL, 15 mmol, 10M) in THF (3 mL) and stirred for 1 h to afford a 0.83 M THF solution of disiamylborane. In a separate flask, disiamylborane (0.1 mL, 0.08 mmol) was added to 6-allyl-6-(4-fluorophenyl)-3-(methyl(phenyl)amino)-1,3-oxazinan-2-one (6 mg, 0.018 mmol) in THF (1 mL) at 0° C. The reaction was warmed to rt overnight. The reaction was cooled to 0° C. and quenched with H2O (1 mL) and stirred for 15 min at rt. NaBO3 (22 mg, 0.22 mmol) was added and the reaction was stirred for 2 h. The solvent was evaporated and the crude material purified by prep HPLC to afford 6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-(methyl(phenyl)amino)-1,3-oxazinan-2-one (1.16 mg). LC/MS Method 1 tR=1.51 min m/z=359 (M+1).
