To a solution of 5-{3-[2-ethyl-3-(2-oxoethyl)phenyl]-1,2,4-thiadiazol-5-yl}-2-(2-methylpropyl)benzonitrile (D62) (100 mg, 0.257 mmol) and L-proline (59.1 mg, 0.513 mmol) stirred in Ethanol (10 mL) for 20 min was added sodium cyanoborohydride (48.4 mg, 0.770 mmol). This mixture was stirred at room temperature for 2 h. The reaction was quenched with water, then dried and dissolved in DMF. The residue was purified by for Mass Directed AutoPrep to afford 1-[2-(3-{5-[3-cyano-4-(2-methylpropyl)phenyl]-1,2,4-thiadiazol-3-yl}-2-ethylphenyl)ethyl]-L-proline (E76) (20 mg) as a TFA salt (white solid).
