Procedure

To a solution of ester 58 (220 mg, 0.68 mmol) in 1:1 H2O/EtOH (9 mL), 4M aq NaOH (10 eq) was added and the mixture stirred at 100° C. for 1 h. After cooling to rt, the solution was acidified with 2M HCl yielding 5-(2-amino-pyrimidin-4-yl)-2-phenyl-thiophene-3-carboxylic acid as a solid which was filtered, washed with water and dried under reduced pressure (185 mg, 90%).
