Reaction Steps

A mixture of 1,4-diiodobutane (13.5 μL, 0.000100 mol), (5S)-7-(4-amino-2-fluorophenyl)-2-(trans-4-hydroxycyclohexyl)-2,7-diazaspiro[4.5]decan-1-one (28.9 mg, 0.0000800 mol, this compound was prepared by using procedures analogous to that described for the synthesis of example 105, step 1 starting from (5S)-2-(trans-4-hydroxycyclohexyl)-2,7-diazaspiro[4.5]decan-1-one) and 4-dimethylaminopyridine (14.7 mg, 0.000120 mol) in DMF (1.00 mL), and potassium iodide (1.5 mg, 0.0000090 mol) was heated at 110° C. by microwave for 15 min. The mixture was diluted with methanol (0.8 mL) and was adjusted to be acidic with TFA (the pH was about 2.0). The resulting solution was purified by prep-HPLC to give the desired product. LC-MS: 416.2 (M+H)+.
