Abstract
1,138,171. Nitro dyes. L’OREAL. 26 April, 1966 [26 April, 1965], No. 18289/66. Heading C4P. [Also in Division D1] 1 – Amino – 2 – nitro – 4 – (# – hydroxyethyl)- methylamino benzene is prepared by nitrating 1 – acetamido – 4 – (# – hydroxyethyl) – methylamino-benzene and de-acetylating the product. 1 – Methylamino – 2 – nitro – 4 – (# – hydroxyethyl)-methylamino is prepared by methylating the l-amino group of the above product after first protecting one of the hydrogen atoms of the said amino group and then removing the protecting group, e.g. a toxyl group. 1-(#- Hydroxyethyl) – amino – 2 – nitro – 4 – (#- hydroxyethyl) – methylamino benzene is prepared by reacting the first product above with chloroethyl-chloroformate and hydrolysing the product.
