Iodoethane → HCID 9933783, compound

Participants

Reaction Steps

A solution of 1.12 mL (0.559 mmol) of 0.5 M potassium bis(trimethylsilyl)amide in toluene was added to a solution of 0.16 g (0.373 mmol) of the product of Example 1 and 0.149 mL (1.86 mmol) iodoethane in 3.5 mL dry THF+0.13 mL (0.746 mmol) HMPA. The reaction was refluxed overnight, quenched with aqueous NH4Cl, extracted 4× with ether, washed 3× with H2O, dried and concentrated in vacuo to an oil. Purification on Analtech 2 mm prep plates, developed in 15% acetone-petroleum ether, afforded 143 mg (84%) of sticky glassy resin. (−)-Electrospray mass spec (M+35 490) was consistent with the structure.
