Participants

Conditions

Temperature: 180 °C

Procedure

50 mg (0.16 mmol) of the compound from Example 21A were taken up in 1 ml of DMF, 62 mg (0.24 mmol) of 3-[3-(trifluoromethyl)phenyl]propaneimidamide hydrochloride were added and the mixture was stirred in a microwave oven at 180° C. for 1 h. After cooling, the reaction mixture was diluted with methanol and the solution was directly separated by preparative HPLC [Method 19]. This gave 11 mg (14% of theory) of the title compound.
