2-[3,5-bis(trifluoromethyl)phenyl]-N-[6-[(7S,9aS)-7-({[(1,1-dimethylethyl)(dimethyl)silyl]oxy}methyl)hexahydropyrazino[2,1-c][1,4]oxazin-8(1H)-yl]-4-(2-formylphenyl)-3-pyridinyl]-N,2-dimethylpropanamide (D60, 27.7 mg, 0.0356 mmol) was suspended in dry THF (1.5 mL) before adding sodium borohydride (3 mg, 0.078 mmol) and stirring for 1 hour. Added more sodium borohydride (3 mg, 0.078 mmol) and left stirring for a further 1 and ½ hours. Reaction quenched with water, diluted with EtOAc. Organic layer washed with water, dried (MgSO4). Filtered. Solvent evaporated to afford the title compound as an off white solid in 89% yield. Used crude in the next step.
