Procedure

1.3 g (7.5 mmol) of the compound from Example 4A and 1.4 ml (1.2 g, 8.2 mmol) of N,N-dimethylformamide diethyl acetal are stirred at a bath temperature of 100° C. for 16 h. For work-up, the cooled reaction solution is concentrated on a rotary evaporator and the residue is dried under reduced pressure. Yield: 1.5 g (86% of theory)
