This is one of many Guinness clone recipes out on the internet, how to convert this to a syrup?

(5 gallons/19 L, extract with grains)
OG = 1.038 FG = 1.006
IBU = 45 SRM = 40 ABV = 4.2%
[h5]Ingredients[/h5]
14.5 oz. (411 g) Muntons Light dried malt extract
2.66 lbs. (1.21 kg) Muntons Light liquid malt extract (late addition)
1 lbs. 6 oz. (0.62 kg) English pale ale malt (3 °L)
10 oz. (0.28 kg) flaked barley
1.0 lb. (0.45 kg) roasted barley (500 °L)
12 AAU East Kent Goldings hops (60 min) (2.4 oz./68 g of 5% alpha acids)
Wyeast 1084 (Irish Ale) or White Labs WLP004 (Irish Ale) yeast (2 qt./2 L yeast starter)
0.75 cups corn sugar (for priming)
[h5]Step by Step[/h5]
Place crushed grains and flaked barley in a steeping bag. In a large kitchen pot, heat 4.5 qts. (4.3 L) to 161 °F (72 °C) and submerge grain bag. Let grains steep for 45 minutes at around 150 °F (66 °C). While grains are steeping, begin heating 2.1 gallons (7.9 L) of water in your brewpot. When steep is over, remove 1.25 qts. (1.2 L) of water from brewpot and add to the "grain tea" in steeping pot. Place colander over brewpot and place steeping bag in it. Pour diluted grain tea through grain bag. Heat liquid in brewpot to a boil, then stir in dried malt extract and hops and begin the 60 minute boil. With 15 minutes left in boil, turn off heat and stir in liquid malt extract. Stir well to dissolve extract, then resume heating. (Keep the boil clock running while you stir.) At the end of the boil, cool wort and transfer to fermenter. Add water to make 5 gallons (19 L), aerate wort and pitch yeast. Ferment at 72 °F (22 °C). Rack to secondary when fermentation is complete. Bottle when beer falls clear.
Wang, Dang, Sweet Guinness Tang
To get that "Guinness tang," try this. After pitching the yeast to your stout, siphon 19 oz. of pitched wort to a sanitized 22 oz. bottle. Pitch bottle with a small amount of Brettanomyces and Lactobacillus. Cover bottle with aluminum foil and let ferment. When beer in bottle is done fermenting, pour it in a saucepan and heat to 160 °F (71 °C) for 15 minutes. Cool the beer and pour and pour it back in the bottle. Cap bottle and refrigerate. Add to stout when bottling or kegging.
