Procedure

NaH, 60% (0.236 mol) was stirred in DMF (500 ml), at room temperature. 3-amino-4-chloro-2-methylphenol (0.236 mol) was added portionwise (exothermic temperature rise to 32° C.). The reaction mixture was stirred for 30 minutes, allowing the temperature to drop to room temperature. Iodomethane (0.236 mol) was added dropwise. The reaction mixture was stirred for one hour at room temperature. Water was added (at first, slowly). This mixture was extracted with toluene. The separated organic layer was dried, filtered and the solvent evaporated, yielding 40.5 g 6-chloro-3-methoxy-2-methylbenzenamine (interm. 22) (quantitative yield; used in next reaction step, without further purification).
