実験手順

To a solution of 3-[5-chloro-2-methyl-4-(2-methyl-thiazol-4-ylmethoxy)-6-oxo-6H-pyrimidin-1-yl]-N-methoxy-4,N-dimethyl-benzamide from Step B (93 mg, 0.21 mmol) in tetrahydrofuran (2 mL), cooled using an ice water bath, was added ethynylmagnesium bromide, 0.5M in tetrahydrofuran, (0.62 mL, 0.31 mmol) in a drop-wise manner. Additional Grignard reagent was added as necessary to ensure full product formation. After thirty minutes, the reaction was quenched into ice cold water and extracted with ethyl acetate. The organic layer was washed with saturated ammonium chloride, water and brine and dried over magnesium sulfate. The slurry was filtered and concentrated. The crude material was used without any additional purification.
