ABSTRACT:
The present invention relates to a process for preparing a compound of formula (Ia), (Ib), (Ic) or (Id), or a pharmaceutically acceptable salt, hydrate, solvate, complex or prodrug thereof, said process comprising the steps of: (A) (i) treating a compound of formula (IVa), where R48is alkyl or tosyl, with an oxidizing agent to form a compound of formula (Va); and (ii) converting said compound of formula (Va) to a compound of formula (Ia) or (Ic); or (B) (i) treating a compound of formula (IVb), where R48is alkyl or tosyl, with an oxidizing agent to form a compound of formula (Vb); and (ii) converting said compound of formula (Vb) to a compound of formula (Ib) or (Id).
