Reaction Steps
This compound is prepared by the procedure described in EXAMPLE 100 starting from 1 g of the compound obtained in EXAMPLE 13, 0.3 g of 2-aminothiazole, 1.2 g of BOP, 1 ml of DIPEA and 20 ml of DCM. It is chromatographed on silica using a DCM/MeOH mixture (99.5/0.5; v/v) as the eluent to give 0.09 g of the expected product after crystallization from EtOH. M.p.=213° C.
