Reaction Steps

A solution of the product of Step H (405 mg, 0.83 mmol, 1 eq) and 5% Pd/C (100 mg) in ethanol (10 mL) at rt was placed under a balloon of hydrogen gas overnight. The suspension was filtered through celite, washed with methanol, and the filtrates concentrated to give the product of Step I as a gum. Calculated for C18H31N3O4: 354.2 (M+1). found: 354.2.
