Procedure

To [2-Chloro-6-(4-chloro-benzylamino)-pyridin-3-yl]-(1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (P-0048, 0.045 g, 0.00011 mol, prepared as described in Example 27) was added methanol (10 mL) and sodium borohydride (0.00428 g, 0.000113 mol). The reaction was allowed to stir at 50° C. overnight. The volatiles were removed from the reaction, and the resulting material was extracted with ethyl acetate and 1M aqueous sodium bicarbonate. The organic layer was dried over magnesium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with dichloromethane followed by 1% methanol in dichloromethane to give the compound (P-0050, 31 mg, 68%). MS (ESI) [M+H+]+=399.2.
