Reaction Steps
The title compound is prepared by treating 2-n-butyl-3-(2'-(tetrazol-5-yl)-biphen-4-yl)methyl-5-ethoxycarbonylpyrimidin-4(3H)-one (from Example 8) with an ester hydrolyzing agent such as sodium hydroxide in an appropriate solvent such as methanol, possibly with heating. Addition of water, acidification with concentrated HCl, saturation with NaCl, extraction with ether, washing of the combined organic extracts with brine, drying of the organic material over an appropriate drying agent such as MgSO4, and stripping of solvent in vacuo should give the crude organic acid which may then be purified by appropriate means such as silica gel chromatography. Alternatively, the ester from Example 8 is hydrolyzed using an appropriate esterase such as pig liver esterase followed by standard purification procedures.
