It was a good batting show by the visitors ahead of the Test series against India as four batsmen from the Caribbean side scored half-centuries.
Chanderpaul and Deonarine (83) will resume their fifth- wicket partnership tomorrow.
After Chris Gayle's failure, Kieran Powell (64) and Darren Bravo (61) built the innings with a 112-run second wicket partnership but the Piyush Chawla-led UP side had a two-wicket burst to leave the visitors 149/3 at the midway stage.
There was some excitement in the air after Darren Sammy opted to bat to have the first feel of the conditions but Gayle's was a subdued knock that lasted only 25 balls. He was beaten by an Imtiaz Ahmed in-swinger that stayed low before skidding onto his stumps.
The UP medium-pacer who came in as the first change got rid of the explosive opener in a fine first spell of four overs that had three maidens and the prized scalp.
