Methyl iodide → HCID 70188013, compound

Participants

Reaction Steps

60% Sodium hydride (10.2 mg) was added to a stirred solution of benzhydryl N-[[1,2,3,4-tetrahydro-5-(methoxycarbonylmethoxy)-2-naphthyl]methyl]carbamate (117 mg) and methyl iodide (36 mg) in N,N-dimethylformamide (1.2 ml) under ice cooling and the mixture was stirred at the same temperature for 7 hours, then another 60% sodium hydride (10.2 mg) and methyl iodide (36 mg) was added thereto. The resulting mixture was stirred at room temperature for 3 days and extracted with ethyl acetate. The extract was washed twice with brine, dried over magnesium sulfate, and evaporated in vacuo. The residue was chromatographed (toluene-ethyl acetate) over silica gel to afford benzhydryl N-methyl-N-[[1,2,3,4-tetrahydro-5-(methoxycarbonylmethoxy)-2-naphthyl]methyl]carbamate (71 mg) as an oil.
