Reaction Steps

(5-Cyanomethyl-1,3-benzodioxol-4-yl)acetonitrile (6.00 g, 30.0 mmoles) from Example 58C was reductively cyclized with Raney Nickel (1.21 g) under a hydrogen atmosphere and high pressure (1100 p.s.i.) in a 10% ammonia in ethanol solution (121 mL) at 100° C. for one hour. The mixture was cooled, and the catalyst filtered off and washed with hot ethanol. The mixture was concentrated under reduced pressure, and the residue purified by normal phase HPLC on a Biotage pre-packed silica gel column eluting with 7:3 methylene chloride:methanol to afford the title compound. MS(DCI) m/z 192 (M+H)+.
