Reaction Conditions:
Stage #1: 4-iodo-7H-pyrrolo[2,3-d]pyrimidinewith potassium carbonate in N,N-dimethyl-formamide at 20; for 0.5 h;
Stage #2: (2-trimethylethylsilylethoxy)methyl chloride in N,N-dimethyl-formamide at 20; for 6 h;
Steps:
1.2 Step 2: Synthesis of Compound 1C
K2CO3 (2g, 14.6mmol) was added to a solution of 4-iodo-7H-pyrrolo[2,3-d]pyrimidine (1.79g, 7.31mmol) in anhydrous DMF. It was then stirred at room temperature for 30 minutes. After 30 minutes, 2-(trimethylsilyl)ethoxymethyl chloride (1.35 g, 7.31 mmol, 1.44 ml) was added dropwise to the solution. The reaction was stirred at room temperature for 6 hours.TLC showed the reaction was over. The reaction was quenched by the addition of saturated aqueous NH4Cl. Extract with ethyl acetate (3 × 10 mL), combine the organic phases and dry over anhydrous sodium sulfate, filter to remove the desiccant, desolvate under reduced pressure, and purify the residue by silica gel column chromatography (petroleum ether / ethyl acetate = 10: 1 to 3: 1 (volume ratio V: V)) to obtain the target compound 1C (2.2 g, yellow oil) in a yield of 80%.
