Procedure

5-Bromothiophene-3-carboxylic acid (0.5 g, 2.4 mmol) was dissolved in acetonitrile (10 mL) and triethylamine (7.1 mmol). Decahydroquinoline (3:2 mixture of cis- and trans-isomers; 4.8 mmol) and HATU (2.4 mmol) were added and the reaction stirred at room temperature overnight. The solvent was evaporated and the residue dissolved in DCM and washed with water. After drying with anhydrous magnesium sulphate, the solution was filtered and evaporated and the residue purified by flash chromatography on silica, eluting with 0-40% ethyl acetate in cyclohexane. The fractions containing the desired product were combined and evaporated to give the title compound as a white crystalline solid (0.39 g). LCMS m/z 330.11 [M+H]+ RT=4.07 min (Analytical Method 4).
