Participants

Reaction Steps

To the solution of 2-methylsulfanyl-4-(3-hydroxypropyl)-6-(3,4-dimethyl-phenyl)pyrimidine (5.8 g) in a mixed solvent of methanol and water (110 ml, 10:1) was added OXONE (35 g). The mixture was stirred at room temperature for 3 hours, then diluted with ethyl acetate (500 ml). The mixture was washed with water (3×500 ml). Organic layer dried over sodium sulphate, solvent removed under reduced pressure to give 2-methanesulphonyl-4-(3-hydroxypropyl)-6-(3,4-dimethylphenyl)-pyrimidine as crude product. To a stirred solution of above 2-methylsulphonyl-4-(3-hydroxypropyl)-6-(3,4-dimethylphenyl)pyrimidine in dimethylsulfoxide (50 mL), was added sodium cyanide (2.9 g). The mixture was stirred at room temperature for 4 hours, then poured into ethyl acetate (300 mL) and washed with water (2×200 mL). The organic layer was dried over sodium sulphate, solvent evaporated at reduced pressure, the above residue was flashed on silica gel using Petrol/EtOAc (1:1) as eluent to give 4-(3-Hydroxy-propyl)-6-(3,4-dimethylphenyl)-pyrimidine-2-carbonitrile as product (4.8 g).
