Reaction Conditions

Reaction Steps

To a solution of 3.43 g of 1-[(2'-tert-butoxycarbonylbiphenyl-4-yl)methyl]-4-methyl-2-propylimidazole-5-carboxaldehyde (from Example 320, Part D) in 22 mL of methanol and 22 mL of tetrahydrofuran at 25° C. was added in several portions, 3.09 g of sodium borohydride. The reaction mixture was stirred at 25° C. for 1.5 hours and then was poured into dilute aqueous sodium hydroxide solution. After stirring for 0.2 hour at 25° C. this solution was extracted with chloroform. The combined organic phases were washed with water and brine, dried over anhydrous sodium sulfate, filtered, and concentrated. Column chromatography (elution: ethyl acetate/benzene) furnished 3.32 g of 1-[(2'-tert-butoxycarbonylbiphenyl-4-yl)methyl]-5-hydroxymethyl-4-methyl-2-propylimidazole.
