Methods of producing compounds that stimulate hair regrowth, topical formulations, and methods of use

A method of producing a composition for hair regrowth, wherein the composition comprises a compound having a structure according to Formula (I)

• the method comprising:
• (1) adding a Friedel-Crafts catalyst to a 1,2-dichloroalkane to generate a first intermediate at a first temperature, wherein the first temperature is between −10 and 15 degrees Celsius, inclusive
• (2) adding the first intermediate to an alkylbenzene at the first temperature and to generate a second intermediate;
• (3) cooling the second intermediate to a second temperature to generate a third intermediate, wherein the second temperature is between −90 and −70 degrees Celsius, inclusive;
• (4) incubating the third intermediate at the second temperature for a first duration;
• (5) warming the third intermediate to a third temperature and incubating the third intermediate at the third temperature for a second duration, wherein the third temperature is between 30 and 50 degrees Celsius, inclusive;
• (6) cooling the third intermediate to the second temperature and incubating the third intermediate at the second temperature for a third duration;
• and
• (7) repeating steps (5) and (6) at least four times.
