Procedure

A mixture of 2,6-dichloro-4-(2,3-epoxypropoxy)benzaldehyde (3 gm) and tert-butylamine (20 ml) is heated at 45° for 17 hours. The excess tert-butylamine is removed under reduced pressure (20 mm). The oil is dissolved in 6N hydrochloric acid (25 ml) and heated for 1 hours. The acid solution is added to boiling saturated aqueous sodium carbonate with nitrogen ebullition. The basic solution is extracted with chloroform. The chloroform is dried over anhydrous sodium sulfate, filtered and concentrated to 2,6-dichloro-4-(3-tert-butylamino-2-hydroxypropoxy)benzaldehyde which is used without further purification.
