Sodium borohydride → HCID 59598494, compound

Participants

Reaction Steps

To a solution of (R)-tert-butyl 2-((S)-(2-ethoxy-2-oxoethoxy)(6-fluoro-3′-methylbiphenyl-2-yl)methyl)morpholine-4-carboxylate (570 mg, 1.17 mmol) in CH3OH (20 mL) at rt, NaBH4 (355 mg, 9.36 mmol) was added in portions. The mixture was stirred for ˜0.5 h at rt and then evaporated. The residue was partitioned between water and EtOAc. The combined organic layers were washed with brine, dried over anhydrous NaSO4 and evaporated to give semi-crude (R)-tert-butyl 2-((S)-(6-fluoro-3′-methylbiphenyl-2-yl)(2-hydroxyethoxy)methyl)morpholine-4-carboxylate (498 mg, 96%), which was used in the next step reaction without further purification. MS (E/Z): 446 (M+H+)
