Versuchsvorschrift
5-(Bromoacetyl)-2-hydroxybenzaldehyde (109g) is suspended in 2-propanol (920ml) and cooled to -3° C. with stirring. The reaction mixture is treated with 1,1dimethylethanamine (29.24g) and stirred at -3° C. to 0° C. for 30 minutes whereupon precipitation occurs. The reaction mixture is allowed to warm to room temperature, stirred for 90 minutes then cooled to 10° C. and filtered. The solid obtained is washed with ice cold 2-propanol (2×100ml) and dried in vacuo at 55° C for 18 hours providing 89g of 2-bromo-1-[3-[[(1,1-dimethylethyl)imino]methyl]-4-hydroxyphenyl]ethanone.
