Participants

Conditions

Temperature: 52.5 °C

Procedure

130 g (179 mmol) of the compound from Example 67A are dissolved in 650 ml of ethanol, 193 ml (2.68 mol) of a 40% strength aqueous methanamine solution are added and the mixture is heated at 50-55° C. for one hour. After cooling to room temperature, water and dichloromethane are added, the phases are separated and the organic phase is dried over sodium sulphate. After filtration, the mixture is evaporated to dryness under reduced pressure. The residue (117 g, 89% of theory) is reacted further without further purification.
