Procedure

A solution containing 0.5 g of the product obtained in Example 24 in 2.5 mlof thionyl chloride was refluxed for 10 min. The excess of thionyl chloridewas evaporated in vacuo and the residue dissolved in 25 ml of dichloromethane. To this solution 0.47 g of isopropylamine was added and the mixture was Stirred for 1 h at 20° C. Dichloromethane phase waswashed with 1 N hydrochloric acid and evaporated in vacuo. The residue was crystallized from toluene. Yield 0.44 g (75%), m.p. 113°-115° C.
