The invention relates to compounds of the formula I
in which R1, R2, A, B, X and Y have the meanings indicated in the claims, and/or a pharmaceutically acceptable salt and/or a prodrug thereof. Because of their properties as inhibitors of chemokine receptors, especially as CXCR2 inhibitors, the compounds of the formula I and the pharmaceutically acceptable salts and prodrugs thereof are suitable for the prevention and treatment of chemokine mediated diseases.

Methoxymethyl-2-pyridylsulfide (MOM-ON) is an effective methoxymethylating reagent when used in conjunction with AgOTf, NaOAc, and THF. A wide range of MOM ethers are produced from corresponding phenols and alcohols, including tertiary and allylic alcohols, in good yields and under mild, neutral conditions. This method is also effective for the methoxymethylation of avermectin aglycones.
