Procedure

40% aqueous methylamine solution (3.50 mL, 40.1 mmol) was added in drops to a mixture of 4N hydrochloric acid (1.98 mL) and methanol (2.3 mL) with ice cooling. A solution of the title compound from step 2 (2.00 mg, 8.09 mmol) in methanol (30 mL) and potassium cyanide (1.32 g, 20.3 mmol) were then added. The mixture was stirred for 3 d at RT and then after adding water (10 mL) was extracted 4× with ether. The combined organic phases were dried over Na2SO4 and concentrated to low volume in a vacuum.
