Procedure

A mixture of 2-(2-o-tolylamino-benzoxazol-6-yl)acetic acid (0.398 g, Reference Example 2), O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (0.59 g) and diisopropylethylamine (0.24 g) in dimethylformamide was stirred at room temperature for 10 minutes and then treated with a solution of ethyl 3-[7-amino-indan-4-yl]-butanoate hydrochloride (0.4 g, Reference Example 5) in dimethylformamide. After shaking and then allowing to stand at room temperature for 16 hours the reaction mixture was evaporated under high vacuum. The residual red oil was dissolved in ethyl acetate and the solution was washed with 5% aqueous sodium bicarbonate, then with water, then dried over sodium sulfate and then evaporated to give the title compound (0.754 g) as an oil.
