Hydrochloric Acid → HCID 59536788, compound

Participants

Reaction Steps

Of the compound from Example 40A, 192 mg (0.63 mmol) were introduced in 11 ml of water/methanol 1:2 and admixed in succession at RT with 0.63 ml (0.63 mmol) of 1M hydrochloric acid and 166 mg (2.05 mmol) of potassium cyanate. The reaction mixture was stirred at RT overnight and then freed from the methanol on a rotary evaporator. The residue was taken up in DMSO and purified by preparative HPLC [Method 20]. The product fraction was concentrated on a rotary evaporator. Drying of the residue in an HV gave 177 mg (73% of theory) of the title compound.
