Reaction Steps

Next, 300 mg of the above product (S)-β-[(1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl)amino]benzenepropanol was dissolved in 15 ml CH2Cl2 followed by addition of 0.44 ml SOCl2. The reaction was heated to reflux for 3.5 hours. The solvent was then removed under a stream of nitrogen. The white solid was recrystallized from about 30% isopropyl alcohol/hexane followed by a second recrystallization from about 5% MeOH/butanone to yield 45 mg of (S)-2,7-dihydro-7-phenyl-2-(phenylmethyl)-3H-imidazo[1,2-c]pyrazolo[4,3-e]pyrimidine after drying under vacuum at 39° C. for 5 days (m.p. 255° C.).
