실험 절차

A solution of 2-o-tolylaminobenzoxazole-6-acetic acid (0.124 g) and diisopropylethylamine (0.17 g) in dimethylformamide (2 mL) was treated with a solution of O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (0.183 g) in dimethylformamide. After 10 minutes at room temperature this yellow solution was added dropwise to a rapidly stirred solution of 3-(1,2,3,4-tetrahydro-isoquinolin-7-yl)-3-(pyrid-4-yl)-propionic acid ethyl ester, enantiomer A {0.219 mmoles, Reference Example 17(a)} in dimethylformamide. After stirring at room temperature for 2.5 hours the reaction mixture was evaporated. The residual oil was dissolved in a mixture of acetonitrile, water and trifluoroacetic acid (25:75:0.1) and treated with dimethylformamide and trifluoroacetic acid to bring to pH2. This mixture was subjected to preparative HPLC {Hypersil Elite C18 column, 10 cm×2.1 cm, using a mixture of acetonitrile, water and trifluoroacetic acid (25:75:0.1) as the mobile phase followed by a 1% acetonitrile/minute gradient) to give the title compound. LC-MS:MS (ES)=575 (M+H)+, 573 (M−H)−.
