Lithium borohydride → HCID 57947746, compound

Participants

Reaction Steps

To a solution of (S)-methyl 5-(3-(2-chloro-4-fluorobenzyl)-1-methylureido)-6-(isoquinolin-3-ylcarbamoyloxy)hexanoate (80 mg, 0.15 mmol) in MeOH (1 mL) and THF (1 mL) was added LiBH4 (2 M in THF, 0.3 mL, 4 equiv.) dropwise. The reaction was stirred at RT for 2 h. The reaction was quenched with saturated NH4Cl (5 mL). The mixture was extracted with EtOAc (10 mL). The organic layer was concentrated. The resulting residue was purified on RP-HPLC using a mixture of acetonitrile and H2O to give (S)-2-(3-(2-chloro-4-fluorobenzyl)-1-methylureido)-6-hydroxyhexyl isoquinolin-3-ylcarbamate as a white solid 10 (40 mg, 53%). LRMS (M+H+) m/z 503.5.
