Hydrochloric Acid → HCID 87546674, compound

Participants

Reaction Steps

Sodium hydride (95% dry, 129 mg, 5.39 mmol) was added to a stirred solution of EXAMPLE 181A (359 mg, 1.08 mmol) in THF (10 mL) at room temperature. After stirring for 15 min, the mixture was treated with 2-iodopropane (917 mg, 5.39 mmol). After two days at 50° C., additional sodium hydride (26 mg, 1.08 mmol) and 2-iodopropane (366 mg, 2.16 mmol) were added. After stirring for 1 h the reaction mixture was acidified with 2M HCl and water was added. The product was extracted with DCM and dried (sodium sulfate). Evaporation of the solvent gave a residue which was purified by flash chromatography on silica gel eluting with 4% acetone in DCM giving (15 mg, 4%) of an oil which solidified on standing: MS (Ionspray, [M+H]+) m/z 374.
