Participants

Reaction Steps

A solution of 17.87 g (0.056 mole) of 2-iodo-5-methoxy-N,alphadimethylbenzenepropanamine in 58 ml of dry methylene chloride was added dropwise to a cooled (5° C.) solution of 3,4-dimethoxyphenylacetyl chloride in 68 ml of dry methylene chloride over a period of five minutes while stirring under an atmosphere of nitrogen. After about two minutes of stirring, 5.67 g (0.056 mole) of triethylamine was added followed by an additional 20 ml of dry methylene chloride. The reaction mixture was allowed to warm to room temperature while stirring overnight. An additional 80 ml of methylene chloride was added and the mixture washed successively with 200 ml of water, 300 ml of 5% hydrochloric acid, and 200 ml of sodium hydroxide solution. The organic phase was dried over anhydrous magnesium sulfate and evaporated in vacuo to yield 27.5 g (99%) of N-[3-(2-iodo-5-methoxyphenyl)-1-methylpropyl]-3,4-dimethoxy-N-methylbenzeneacetamide as an orange gum, MS (high resolution):
