Reaction Steps

To a solution of N-{4-[6-(2,2-diphenyl-ethylamino)-2-hydrazino-purin-9-yl]-2,3-dihydroxy-cyclopentyl}-propionamide (step 1) (0.1 g, 0.19 mmol) in dry methanol (5 ml) is added cyclohexane carboxaldehyde (0.026 g, 0.23 mmol). The reaction mixture is heated at reflux for 12 h. The reaction mixture is concentrated in vacuo purification by preparative TLC affords the title compound. LC-MS (0.1% formic acid, acetonitrile): (MH+ 611.45)
