Participants

Reaction Steps

(tert-Butoxy)-N-{1-[(4-{[4-(4-chlorophenyl)pyrimidin-2-yl]amino}phenyl)carbonyl](4-piperidyl)}carboxamide (4.00 g, 7.87 mmol) was stirred in 50 mL EtOH followed by addition of anhydrous HCl gas. The reaction was stirred for 30 min. then concentrated down to a residue. To this was added a small amount of EtOH followed by dilution with ether. A yellow solid formed which was filtered and dried to give 3.00 grams of 4-aminopiperidyl 4-{[4-(4-chlorophenyl)pyrimidin-2-yl]amino}phenyl ketone hydrochloride: HPLC Retention time; 5.89 min. (Method B) M+1; 408.4
