実験手順

To a solution of 398 mg of (1S,2S)-6-fluoro-2-[2-({3-[(2-fluoro-ethyl)-(3-methoxy-2-methoxymethyl-2-methyl-propyl)-amino]-propyl}-methyl-amino)-ethyl]-1-isopropyl-1,2,3,4-tetrahydro-naphthalen-2-ol and 0.44 mL of NEt3 in 8 mL of DCM 0.25 mL of isobutyrylchloride was added at 0° C. The mixture was stirred for 25 min at 0° C. and then for 3 h at rt. It was quenched with sat. aqueous NaHCO3 and extracted with DCM. The organic phase was dried over anh. Na2SO4 and concentrated in vacuo. The resulting crude was purified by CC using EtOAc/Hept 3/1 as eluant to yield 411 mg of isobutyric acid (1S,2S)-6-fluoro-2-[2-({3-[(2-fluoro-ethyl)-(3-methoxy-2-methoxymethyl-2-methyl-propyl)-amino]-propyl}-methyl-amino)-ethyl]-1-isopropyl-1,2,3,4-tetrahydro-naphthalen-2-yl ester as orange oil.
