Reaction Steps

2-{1-oxo-7-[3-(trifluoromethoxy)phenyl]-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-4-yl}ethyl methanesulfonate (150 mg, 0.36 mmol) were reacted with sodium azide (60 mg 0.924 mmol) in acetonitrile/DMF 10 ml/2 ml at 80° C. for 18 hours. The reaction was worked up with water, saturated NaHCO3 and extracted with ethyl acetate. The organic phase, dried on Na2SO4, was filtered and evaporated. The crude was dissolved with diethyl ether and after a while, a solid precipitated, which was filtered to give 104 mg (80%) of 4-(2-azidoethyl)-7-[3-(trifluoromethoxy)phenyl]-3,4-dihydropyrrolo[1,2-a]pyrazin-1(2H)-one.
