Preparation of example 61 from the title compound of Example 7 (198 mg, 0.72 mmol), (1R,2R)-2-phenylcyclopropanecarboxylic acid (175 mg, 1.08 mmol; as described by A. Thurkauf, et al., J. Med. Chem. 43, 3923–3932, (2000)), triethylamine (0.401 mL, 2.88 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (411 mg, 1.08 mmol) in N,N-dimethylformamide (10.0 mL) was carried out analogously to Example 11. Silica gel chromatography (3% methanol in CH2Cl2), also in an analogous manner, followed by collection on a frit and subsequent washing with diethyl ether afforded the title compound (86 mg, 0.20 mmol) as a yellow powder in 28% yield.
