실험 절차
To an cooled solution (−78° C. internal temp) of 0.3 g of methyl 4-methoxypyrimidine-5-carboxylate in 20 mL of dichloromethane was added 2 mL of 1 M diisobutyl aluminum hydride in toluene. After stirring 10 min the reaction was quenched with 5 mL of water, allowed to warm to room temperature and dried with 5 g of MgSO4. Concentration of the filtrate under reduced pressure gave the product as a resin and was used without further purification: MS (m+1)=171.1 (hydrate).
