Methyl iodide → HCID 69300194, compound

Participants

Reaction Steps

In 5 mL of DMF, 119 mg (0.22 mmol) of N-(17-cyclopropylmethyl-4,5α-epoxy-14-hydroxy-3-methoxymethoxy-morphinan-6-yl)-3-hydroxy-phthalimide obtained in Example 102-1 was dissolved, and 93 mg of potassium carbonate and 0.02 mL of methyl iodide were added thereto, followed by stirring the mixture at room temperature for 3.5 hours. Aqueous saturated sodium hydrogen carbonate solution was added to this reaction solution, and the resulting mixture was extracted with chloroform. Organic layers were combined, washed with saturated saline, dried over anhydrous magnesium sulfate and concentrated to obtain 112 mg of N-(17-cyclopropylmethyl-4,5α-epoxy-14-hydroxy-3-methoxymethoxy-morphinan-6β-yl)-3-methoxy-phthalimide as a crude product.
