Reaction Steps

A solution of the product from Example 266B (4.1 g, 15.12 mmol) in methanol (10 mL) was added to 7 M ammonia in methanol (5.00 mL) and Raney® nickel, water wet, A-7000 (12.30 g, 210 mmol) in a 250 mL stainless steel pressure bottle and stirred for 16 hours under hydrogen (30 psi) at room temperature. The mixture was filtered through a nylon membrane and then concentrated to obtain solid. The solid was slurried in 5% ethyl acetate/hexanes, filtered and dried to give the title compound. MS (DCI+) m/z 247 (M+NH4)+.
