Hydrochloric Acid → HCID 69893385, compound

Participants

Reaction Steps

0.4 g (0.78 mmol) of the compound from Example 3-7 are dissolved in 4 ml of ethyl acetate. At 40° C., first 8 ml of 1N hydrochloric acid (in diethyl ether) and then 12 ml of diethyl ether are added. The mixture is allowed to stand at 4° C. for one hour. The precipitated crystals are filtered off with suction, washed with a mixture of ethyl acetate and diethyl ether (ratio 1: 1) and then dried at 40° C. under reduced pressure for 20 hours. This gives 0.362 g (84.5% of theory) of the title compound.
