Reaction Conditions

Reaction Steps

Tetrahydro-2H-pyran-2-one (2 ml), N-methylhydrazinecarbothioamide (3.4 g) and acetic acid (0.3 ml) were suspended in methanol (10 ml). The reaction was heated in microwave oven at 120° C. for 20′ followed by further 10′ at 110° C. Acetic acid was added (0.3 ml) and reaction was heated in a microwave oven at 140° C. for 20′, further acetic acid (0.3 ml) was added and the reaction was in a microwave oven at 140° C. for 20′. The solvent was removed under reduced pressure, DCM was added to the crude and solid filtered-off. Solvent was removed under reduced pressure to give a crude product that was purified by flash chromatography on silica gel (DCM/MeOH from 0 to 10%) to give the title compound as a white solid (1 g).
