Benzophenone, 2',5-dichloro-2-methylamino- → 2',5-Dichloro-2-methylaminobenzhydrol

Participants

Reaction Steps

750 mg of sodium borohydride are added in individual portions to a suspension of 2.8 grams of 2-methylamino-2',5-dichlorobenzophenone in 20 ml of methanol. After reaction for about ten minutes, the solvent is evaporated in a vacuum. After absorption in ether, washing with water, and then drying, 2-methylamino-2',5-dichlorobenzhydrol is isolated by crystallization (2.52 g).
