    Robert S. Wilson, Jr., Individually and as Administrator of the Estate of Karen A. Wilson, Deceased, Respondent, v Arthur D. Rosen et al., Defendants and Neurological Associates of Stony Brook, P. C., Appellant.
   In an action to recover damages for medical malpractice, etc., the defendant Neurological Associates of Stony Brook, P. C., appeals from so much of an order of the Supreme Court, Suffolk County (Copertino, J.), entered December 28, 1988, as denied its motion to dismiss the complaint insofar as it is asserted against it for want of prosecution.

Ordered that the appeal is dismissed, with costs.

The original plaintiff Karen Ann Wilson died prior to the issuance of the order denying the appellant’s motion to dismiss the complaint insofar as it is asserted against it for want of prosecution. There was no effective substitution made prior to the issuance of that order as required by CPLR 1015. Thus, the provision of the order appealed from is a nullity and this court has no jurisdiction to entertain the appeal (see, Cooper v Volk, 157 AD2d 766; Homemakers Inc. v Williams, 131 AD2d 636; Weber v Bellinger, 124 AD2d 1009). Mangano, P. J., Kunzeman, Kooper, Sullivan and Ritter, JJ., concur.
