Abstract: [Problems] The present invention provides a superior production method and a superior purification method of compounds effective for the treatment or prophylaxis of pathology showing involvement of uric acid, such as hyperuricemia, gouty tophus, acute gouty arthritis, chronic gouty arthritis, gouty kidney, urolithiasis, renal function disorder, coronary artery disease, ischemic heart disease and the like. [Means] A compound represented by the following formula [2] or a pharmaceutically acceptable salt thereof can be produced by reacting a compound represented by the following formula [3] or a salt thereof with a compound represented by the following formula [4], a salt thereof or a reactive derivative thereof. Moreover, crystallization of a compound represented by the formula [2] can be performed with industrially superior workability, and high quality crystals of a compound represented by the formula [2] can be obtained. wherein each symbol is as defined in the description.

Abstract: A method of controlling an array antenna having a plurality of antenna elements for providing antenna output signals by receiving TDMA burst signals. The method includes a step of estimating a DOA of incident signal based upon the antenna output signals, a step of calculating weights with reference to the estimated DOA, a step of multiplying the antenna output signals by the calculated weights, respectively, and a step of summing the multiplied antenna output signals. The estimating step includes a first step of calculating a phase difference between the output signals of the two antenna elements during burst, a second step of calculating a phase difference between the output signals of the two antenna elements during an interval of bursts, and a third step of calculating a difference between the calculated phase differences.
