Procedure

2-(4-Methoxy-benzyl)-thiazole-4-carboxylic acid (101 mg, 0.405 mmol) and C-[1-(3,4-Dimethoxy-phenyl)-cyclopentyl]-methylamine (96.5 mg, 0.410 mmol) were dissolved in acetonitrile (2 mL) containing triethylamine (84.1 μL, 0.600 mmol). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (171 mg, 0.450 mmol) was added and the solution was allowed to stir for 16 hours. The reaction mixture was evaporated to dryness and purified by column chromatography on silica gel using a gradient of 5-30% ethyl acetate in hexanes. The pure fractions were combined and evaporated to dryness to yield a yellow solid (84.0 mg, 0.180 mmol, 43.9%). ESI-MS m/z calc. 466.6, found 467.2 (M+1)+. Retention time of 8.32 minutes. 1H NMR (400 MHz, CD3CN) δ1.68-2.07 (m, 8H), 3.50 (d, J=6.3 Hz, 2H), 3.82 (s, 9H), 4.20 (s, 2H), 6.83-7.29 (m, 8H), 7.87 (s, 1H).
