With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.10320-42-0, name is 2-Chloro-5-nitropyrimidine, molecular formula is C4H2ClN3O2, molecular weight is 159.5306, as common compound, the synthetic route is as follows.Safety of 2-Chloro-5-nitropyrimidine

Intermediate 1895-nitro-2-[(3,3 -trimethyl-2,3-dihvdro-l-benzofuran-4-yl)oxylpyrimidine3,3,7-Trimethyl-2,3-dihydro-l-benzofuran-4-ol (Intermediate 184, 178 mg, 1.0 mmol) and 2-chloro-5- nitropyrimidine (191.5 mg, 1.2 mmol) were dissolved in CH3CN (3.0 mL) and K2C03 (345.5 mg, 2.5 mmol) was added. The resulting suspension was heated to 40°C and stirred for 1 hour. The reaction mixture was then diluted with water (50 mL) and ethyl acetate (50 mL), The organic phase wascollected, washed with brine (50 mL) and dried over Na2S04. The residue was purified by flash chromatography on silica gel using cyclohexane/ ethyl acetate 97:3 as eluents affording the title compound (243 mg).
