This is essentially Hironaka's 3-dimensional example, which locally looks like the blow-up of ℙ² along two lines which intersect in two points (but the blow-up is done "in the wrong order" at one of them). Here, you just take the "exceptional locus" (the surface lying over the two lines) and use the same proof to show that it's not projective. | |
