Procedure

Preparation of example 21 from the title compound of Example 7 (hydrochloride) (22 mg, 0.080 mmol), n-butyric acid (0.007 mL, 0.080 mmol), triethylamine (0.014 mL, 0.10 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (32 mg, 0.084 mmol) in CH2Cl2 (0.3 mL) and N,N-dimethylformamide (0.3 mL) was carried out analogously to Example 11. Silica gel chromatography (10:9:1 hexane:CH2Cl2:methanol followed by 9:5:1 CH2Cl2:hexane:methanol), also in an analogous manner, afforded the title compound (14 mg, 0.04 mmol) as a yellow powder in 50% yield.
