Allyl iodide → HCID 90067174, compound

Participants

Reaction Steps

Allyl iodide (130 μl, 1.422 mmol) and sodium hydride (16.0 mg, 0.400 mmol) were added to a stirred solution of (3R,3aR,6R,6aR)-6-[6-chloro-5-(4-phenylphenyl)-1-(2-trimethylsilylethoxymethyl)imidazo[4,5-b]pyridin-2-yl]oxy-2,3,3a,5,6,6a-hexahydro-furo[3,2-b]furan-3-ol (82.8 mg, 0.143 mmol) in DMF (1.4 ml). The reaction mixture was stirred at room temperature for 3 h. The reaction mixture was partitioned between EtOAc (75 ml), water (20 ml), and 2 N HCl (10 ml). The organic layer was washed with water (2×30 ml, brine was added to each wash to break an emulsion) and brine (1×20 ml), dried over MgSO4, filtered, and evaporated under reduced pressure to give an amber residue. Flash chromatography of the residue utilizing a 4 g silica RediSep Rf® column and employing a 0-40% EtOAc/hexane gradient followed by 40% EtOAc/hexane afforded the title compound as a pale yellow solid. LC-MS: calculated for C33H38ClN3O5Si 619.23 observed m/e: 620.32 (M+H)+ (Rt 1.43/2 min).
