2′-Acetylamino-4′-methyl-[4,5′]bithiazolyl-2-carbonyl chloride, prepared as in Step I of Example 13, described above, (110 mg; 0.36 mmol; 1 eq.), is dissolved in anhydrous THF (10 ml). Under nitrogen, triethylamine (0.08 ml; 0.55 mmol; 1.5 eq) is added. Ammonia (gas) is bubbled during 10 minutes. The flask is closed and the reaction mixture is stirred for 20 additional minutes at RT. The solvents are removed and the crude product is directly purified by preparative HPLC, affording Compound (62) as a white-off solid (25.6 mg; 22%).
