At −10° C., 38 mg (0.63 mmol) of aminoethanol are added to a solution of 56 mg (0.11 mmol) of the compound from Example 11A in 1 ml of DMF. After 30 min at −10° C., the mixture is added to water and then extracted three times with ethyl acetate. The organic phases are combined and then freed from the solvent under reduced pressure. The product is purified by preparative HPLC using an acetonitrile/water mixture. This gives 14.5 mg (26% of theory) of the desired product.
