We present a measurement of time-dependent CP-violating asymmetries in decays of neutral B mesons to the final states D*{sup {-+}}, using approximately 82 million B{bar B} events recorded by the BABAR experiment at the PEP-II e{sup +}e{sup -} storage ring. Events containing these decays are selected with a partial reconstruction technique, in which only the high-momentum {pi}{sup {+-}} from the B decay and the low-momentum {pi}{sup {-+}} from the D*{sup {-+}} decay are used. We measure the amplitude of the asymmetry to be -0.063 {+-} 0.024 (stat.) {+-} 0.014 (syst.) and compute bounds on |sin(2{beta} + {gamma})|.
