Methyl iodide → HCID 13067128, compound

Participants

Reaction Steps

In one portion 1.0 g (2.8 mmol) of 8-chloro-6-(2-chlorophenyl)-4-methoxy-2H,4H-pyrrolo[3,4-d][2]benzazepine was added to a solution of 0.35 g (3.0 mmol) of potassium t-butoxide in 20 ml of dimethylformamide which was cooled to 0°. After stirring for 15 min, 0.3 ml (4.8 mmol) of methyl iodide was added. The mixture was stirred for 5 min, diluted with water and extracted with ether. The ether solution was washed with water, dried over anhydrous sodium sulfate, and concentrated at reduced pressure to give a pale yellow oil. Purification by column chromatography (silica gel, 25 g; 5% ether in methylene chloride, eluent) gave an off-white solid, mp 128°-130°. Recrystallization from a mixture of ether and petroleum ether gave off-white prisms, mp 128°-130°.
