The purpose of this paper is to construct a new example of a non-projective smooth Moishezon compactification (X, Y) of C 3 with the second Betti number b2 (X)= 1. In Appendix, we shall give a proof of the following theorem which we need in Sect. 3:Theorem 0 (Peternell). Let iX, Y) be a smooth non-projective Moishezon compactification of C 3 with b2 (X)= 1. Assume that Y is nef Then (0.1) Y is a big and semi-ample irreducible divisor on X.(0.2) there exists a small birational contraction~: X--~ V such that (1) the exceptional set of~ consists of finitely many smooth rational curves Ci (1<-i<-N) supported in Y, and
