Sodium Hydroxide → HCID 22273502, compound

Participants

Reaction Steps

Sodium hydroxide (1.2 g, 3.0 mmole) was added to a solution of 4-(1,2-dimethyl-imidazol-5-yl)-2-(4-acetamidoanilino)pyrimidine (Example 164; 1.25 g, 3.88 mmole) in isopropanol (12 mL) and water (0.5 mL) and the mixture heated under reflux for 90 minutes. The mixture was allowed to cool and was partitioned between saturated aqueous sodium hydrogen carbonate solution and EtOAc. The organic layer was separated and the volatiles evaporated. The residue was purified by column chromatography on silica gel eluting with DCM/7M methanolic ammonia (96:4) to give the title compound (0.75 g, 69%) as a brown solid. NMR: 2.33 (s, 3H), 3.85 (s, 3H), 4.75 (brs, 2H), 6.51 (d, 2H), 6.92 (d, 1H), 7.22 (d, 2H), 7.51 (s, 1H), 8.22 (d, 1H), 8.90 (s, 1H); m/z 281.
