Reaction Steps

The carboxylic acid from Example 156A (60 mg, 0.14 mmol) and HOBt (27.0 mg, 0.20 mmol) are placed in 0.86 ml DMF and treated at RT with 38.2 mg (0.20 mmol) of EDC. After 20 mins, 27 mg of 2-(2-trifluoromethyl-phenyl)ethylamine (0.14 mmol) are added and the mixture is stirred overnight at RT. The mixture is then directly separated by preparative HPLC (Method 20). 69 mg (91% of theory) of the title compound are obtained.
