Alkylation with other alkylating agents such as ethyl iodide (43. 180, 181j, chloracetic acid and its esters (182). and dialkylaminoalkylhalides (40.43) occurs also on the ring nitrogen. [Pg.33]

Benzyl chloride at 175°C appears to alkylate the 5-position of the ring. [Pg.33]

The final product may, however, result from primary nitrogen attack followed by rearrangement (163. 165). [Pg.34]
