Procedure

Preparation of example 16 from the title compound of Example 7 (15 mg, 0.054 mmol), 4-methyl-[1,2,3]thiadiazole-5-carboxylic acid (8 mg, 0.062 mmol), triethylamine (0.030 mL, 0.22 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (25 mg, 0.065 mmol) in N,N-dimethylformamide (1.0 mL) was carried out analogously to Example 11. Additional 4-methyl-[1,2,3]thiadiazole-5-carboxylic acid (1.0 mg, 0.006 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (2.0 mg, 0.006 mmol) were added after c.a. 18 hours to drive the reaction to completion. Silica gel chromatography, also in an analogous manner, followed by diethyl ether trituration afforded the title compound (7 mg, 0.017 mmol) as a yellow powder in 32% yield.
