Procedure
In the same manner as that of the method described in to WO2003/051854, from 4-[3-(2,2-dimethylpropionyl)-5-(2,2-dimethylpropionylamino)-2-phenyl-2,3-dihydro-1,3,4-thiadiazol-2-yl]butanoic acid methyl ester (11.2 g, 25.9 mmol) obtained according to the method described in WO2003/051854 and sodium borohydride (2.94 g, 77.6 mmol), 4-[5-amino-3-(2,2-dimethylpropionyl)-2-phenyl-2,3-dihydro-1,3,4-thiadiazol-2-yl]butanoic acid methyl ester (1.54 g, 17%) was obtained.
