Procedure

To a mixture of ethyl 5,6,7,8-tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine-2-carboxylate (0.033 g, 0.16 mmol) and 5-(2-pyridyl)thiophene-2-carboxylic acid (0.036 g, 0.18 mmol) in methylene chloride (1 mL) was added N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.07 g, 0.184 mmol) and N-methylmorpholine (0.053 mL, 0.48 mmol). The reaction was stirred overnight at room temperature. The reaction was diluted with methylene chloride (3 mL) and washed with saturated aqueous NaHCO3 (2 mL). The aqueous layer was extracted with additional methylene chloride (3 mL). The combined organic layers were dried over anhydrous Na2SO4, filtered and concentrated to dryness to afford Intermediate 31.
