Reaction Steps

A mixture of 0.07 mmol 5-(1-isopropyl-pyrrolidin-3-yloxy)-1H-indole-2-carboxylic acid, 1.25 equiv. 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyl uronium tetrafluoroborat, 1.25 equivalents cyclopropylmethyl-propyl-amine and 5 equivalents N-ethyldiisopropyl-amine in 0.7 ml DMF was stirred for 16 h at room temperature. The mixture was diluted with 0.8 ml methanol and subjected to preparative HPLC purification on reversed phase material eluting with a gradient of acetonitrile/water/triethyamine. The product fractions were evaporated to dryness to yield 9.1 mg (37%) of the title compound as light brown solid. MS (m/e): 384.5 (MH+, 100%).
