Procedure

Preparation of example 12 from the title compound of Example 7 (15 mg, 0.054 mmol), tetrazol-1-yl-acetic 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 tetrazol-1-yl-acetic acid (1.0 mg, 0.008 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (3.0 mg, 0.008 mmol) were added after c.a. 18 hours to drive the reaction to completion. Filtration, concentration and recrystallization afforded the title compound (12 mg, 0.031 mmol) as a yellow powder in 58% yield.
