Reaction Steps

Using the same method as for Example 23, steps 23.a to 23.f, the title compound was synthesised from 4-methoxybenzothiazole, (3R,6S)-(6-formyl-tetrahydro-pyran-3-yl)-carbamic acid tert-butyl ester and 3-oxo-3,4-dihydro-2H-pyrido[3,2-b][1,4]thiazine-6-carbaldehyde. After chromatography on SiO2 (EtOAc/MeOH 9:1 +1% NH4OH) and crystallisation from ether/MeOH, a yellowish solid (30 mg) was obtained.
