Participants

Reaction Steps

0.82 g (1.67 mmol) of the compound from Example 185A was initially charged in 13 ml of dichloromethane, and 1.3 ml (1.90 g, 16.78 mmol) of trifluoroacetic acid were added at RT. The reaction mixture was stirred at RT for 16 h and then concentrated under reduced pressure. The residue was taken up in ethyl acetate, washed with saturated aqueous sodium bicarbonate solution, dried over magnesium sulphate, filtered and concentrated under reduced pressure. Yield: 0.65 g (99% of theory)
