摘要
We describe a new, efficient synthesis of DX-9065 a (4), a potent inhibitor of the blood coagulation enzyme factor Xa (fXa) which has previously been prepared in more than 20 steps. We saved approximately 10 step starting with a Pd-catalyzed cyanation of the triflate 10 of 7-methoxynaphthalen-2-ol (9). After cleavage of the MeO group with boron tribromide. the triflate 6 was coupled to acrylate 5 in a Heck reaction (--> 3). The subsequent transformations led to DX-9065 a.
