Abstract

This invention relates to a novel crystalline form of 6-[(4R)-4-methyl-1,1-dioxido-1,2,6-thiadiazinan-2-yl]isoquinoline-1-carbonitrile which is useful as a selective androgen receptor modulator (SARM), and to compositions thereof and suitable processes for the preparation thereof.

Claims (3)

1. A crystalline form of 6-[(4R)-4-methyl-1,1-dioxido-1,2,6-thiadiazinan-2-yl]isoquinoline-1-carbonitrile having an X-ray powder diffraction pattern with characteristic peaks expressed in degrees 2-theta (±0.2° 2-theta) at 7.8, 10.9 and 15.2.

2. A crystalline form of 6-[(4R)-4-methyl-1,1-dioxido-1,2,6-thiadiazinan-2-yl]isoquinoline-1-carbonitrile according to claim 1 having a further-characteristic peak expressed in degrees 2-theta (±0.2° 2-theta) selected from the group consisting of 17.1, 17.3, and 18.5.

3. A crystalline form of 6-[(4R)-4-methyl-1,1-dioxido-1,2,6-thiadiazinan-2-yl]isoquinoline-1-carbonitrile according to claim 1 or 2 , which crystalline form is anhydrous.
