Procedure

Lithium aluminum hydride (72 mg, 1.9 mmol) is suspended in dry THF (12 ml) under a nitrogen atmosphere. Solid 4-[4-(3-chloro-phenylamino)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-N,N-dimethyl-benzamide (described in WO 97/02266, 140 mg, 0.37 mmol) is added and the mixture heated to 60° C. for 1 h. The reaction mixture is then hydrolized at 0° C. by sequential addition of water (0.072 ml), 15% sodium hydroxide (0.072 ml) and water (0.21 ml). The precipitate is removed by filtration and the filtrate concentrated on a rotary evaporator. The yellow crystalline residue is suspended in methanol, filtered, suspended in toluene, filtered, suspended in methanol again and filtered to give the free base of the title compound [Rf(dichloromethane/methanol 9:1 plus 1 drop of conc. ammonia)=0.36]. This is suspended in methanol (2 ml) and treated with 1 N hydrochloric acid (0.2 ml). The suspension is stirred well and filtered. The crystals are triturated in methanol/water 9:1 and filtered again to give the title compound; m.p. 280-283° C.; MS-ES+: (M+H)+=378.
