Participants

Reaction Steps

A mixture of 0:307 g of the compound of Example 19, 15 ml of methanol and 1 ml of 10N hydrochloric acid is heated at 50° C. for 2 hours. The solvent is evaporated under reduced pressure and the residue obtained is taken up in dichloromethane and water. The organic phase is washed twice with water and then dried over anhydrous sodium sulphate. The solvents are evaporated under reduced pressure. The expected product is isolated after solidifying in cyclohexane, filtering and drying at 30° C. under reduced pressure for 6 hours; M.p.=107° C.
