Procedure

3,3,7-Trimethyl-2,3-dihydro-1-benzofuran-4-ol (Intermediate 27, 178 mg, 1.0 mmol) and 2-chloro-5-nitropyrimidine (191.5 mg, 1.2 mmol) were dissolved in CH3CN (3.0 mL) and K2CO3 (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 was collected, washed with brine (50 mL) and dried over Na2SO4. The residue was purified by flash chromatography on silica gel using cyclohexane/ethyl acetate 97:3 as eluents affording the title compound (243 mg).
