A mixture of 1-[bis(4-cyanophenyl)methyl]-1,2,4-triazole (5.7 g, 20 mmol) with 3 M NaOH (2.4 g, 60 mmol in 20 mL H2O) in DMF (20 mL)was heated at 120°C for 12 h. Then the reaction mixturewas poured onto ice, acidifi ed with conc. HCl to pH 1,saturated with solid NaCl, and extracted with TBME. Theorganic layer was dried over MgSO4. After fi ltration, thesolvent was removed in vacuum to afford the product asoff-white solid, yield 77%. It was used further withoutadditional purifi cation.

97.43 %Spectr. With [Rh(6,7-dihydrotribenzo-[e,i,m][1,4,7,12]-ioxadiazacyclotetradecine)]Cl; water; sodium hydroxide at 70℃; for 0.25h; Hydrolysis of Letrozole In a 100 ml round bottom (RB) flask, 3 ml of LTZ solution (200 lg/ml), 3 ml of NaOH and [Rh(HBACHD)]Cl (Comp.1, 0.02 mmol) were taken and refluxed for 15 min. The contents of RB flask were cooled for 10 min and transferred to 20 ml calibrated tubes. Now, 5 ml of ferric chloride was added to each tube and the total volumes were made up to 20 ml with double distilled water and kept aside for 5 min. The absorbance of the yellow colored solutions was measured at 380 nm against a similar reagent blank (Fig. S1). The amount of HLTZ was assayed from the calibration curve (Fig. S1). The procedure was repeated by changing the rhodium catalysts.
