HCID 69307284(3R)-3-methyl-1-(1H,3H-naphtho[1,8-cd]thiopyran-6-yl)piperazine

Procedure

The procedure used for the synthesis of (3R)-3-methyl-1-(1H,3H-naphtho[1,8-cd]pyran-6-yl)piperazine (Example 5b)) was followed, using 6-bromo-1H,3H-naphtho[1,8-cd]thiopyran as starting material and making non-critical variations, to obtain the title compound (3R)-3-methyl-1-(1H,3H-naphtho[1,8-cd]thiopyran-6-yl)piperazine as brown solid.
