Reaction Steps
3a,4,6,7-Tetrahydro-3-phenyl-7-(phenylmethylene)thiopyrano[4,3-c]pyrazole-2(3H)-ethanol is suspended in pyridine and treated with one equivalent of tosyl chloride. After standing at room temperature for about 16 hours, the mixture is poured into water and the tosylate is dissolved in ethanol, cooled and saturated with ammonia gas. After standing for 3 days, the excess ammonia and solvent are removed by evaporation to give the title compound.
